This is my second sonic toothbrush, first one lasted more than 2 years. This is a great product.

love it, my whole family loves them and we will buy again!

I have rheumatoid arthritis and limited mobility so sometimes brushing can be difficult but the automatic brush and visual aspect on the phone greatly assists me.

I'm not going to lie, I have bout every toothbrush out there and this is the first one that I have actually fell in love with. It is the only one that really deep cleans and you can feel it when you are done. I love everything about it! Including the app that tracks my brushing habits. I am in love with this toothbrush and hope to NEVER part with it.

I've used Sonicare toothbrushes for many years and I must admit, I like my newest one the best of all: Philips Sonicare DiamondClean Smart Sonic electric toothbrush with app HX9903/21.

This toothbrush is so thorough at cleaning and whitening that I don't need any other products to keep my teeth clean and bright.

It's a high quality toothbrush -- well made and easy to keep clean. The brushes themselves are larger than the ones I used to use, and they not only clean my teeth but feel good on the gums.

I am very happy to have invested in a high quality toothbrush such as this one.

I wish I could have gotten a white one. That aside, I think the product does a great cleaning job. My teeth feel very smooth and clean after using it. It also holds a charge for a long time. I have not been able to figure out how to use the app with the toothbrush.

I like different modes on it and how fast it brush

This is the only brush that makes my teeth look and feel clean. In addition, my teeth are much whiter since I started using it four months ago. My sister and brother-in-law got it for my birthday as they knew I had been searching for the perfect toothbrush. They both use one daily and love it too! Now I even travel with it as I was gone for a week traveling without it, and I could not get my teeth to feel clean. I couldn't wait to get home to my Philips DiamondClean Smart! Since then I have traveled with it twice, last thing to pack and first thing to unpack. It travels well in the case that comes with it! Thanks for this fine, dependable product.

I found this toothbrush to be very smart. It cleans well and polishes. My only complaint is that is drains my battery on my phone to sync it during brushing so I do not do that every time.

After the first use it felt like I left the dentist. So I'm very please with the product. I'm going to be purchasing the air floss next

works 10 X better than any other electric toothbrush I have had before ! Even the dentist noticed I really like the charging glass and it holds a charge for over two weeks

This toothbrush is certainly part of my daily routines to keep my teeth and gums healthy. This is my 3rd Sonic that I have purchased over the years. I really like that this one can tie into app on my phone and let me know about brushing effectiveness and time to replace the brush.

Best toothbrush I ever owned! Different Cleaning options leave teeth feeling clean.

This is my 4th Sonicare model in the past 17 years. It’s also my favorite! It’s light in my hand, the prettiest pink, charges easy in its glass cup which also cleans super easy. The brush head design is amazingly perfect for my mouth and thoroughly cleans every inch! I’m extremely happy!

I love this toothbrush. I follow my time on my app. It helps me greatly.

I was very hesitant to buy this toothbrush because of the super high price tag. However, I used several store coupons to receive $10 off and another 20% off. There was also a $60 rebate offer that basically cut the price in half. I was expecting a good brushing but nothing like what it does It makes my teeth and gums feel amazingly clean and I've notices significant whitening after only a few sessions.

This product is as good as having a dental cleaning! I will buying more for family members soon.

My teeth feel very clean and refreshed after! I love all the amenities to the toothbrush! I would highly recommend this product!

My husband got me this toothbrush for Christmas. I didn't expect much, but it's great. I love to use the app and see how well I brushed. I highly recommend it for people that like to get a clean mouth from brushing!

Love the charger and feel. Keep up the good work...

To me, this is the most aesthetically pleasing brush on the market. I was using the original white diamond clean for ages and decided to upgrade to the new pink, partially so my husband and I can tell them apart, and I love this one too. I actually have not used the app. I did start with one whose battery died super quick, but the warranty helped me out and this one has lived on one charge for three weeks. It's best to charge for a full 24 hours before using!!! I'm also super happy with this newest case. I loved the usb charger on my first, but could never find my cord, or would forget it. Now, it's hidden in the base! Super easy.

I LOVE my new toothbrush! It has me brushing my teeth more and I love the app that tells you if your teeth are clean. It is awesome!!

Love using this toothbrush, so easy to use, comfortable and motivates me to brush my teeth even when I am tired and don't feel like it. It is worth the money

Honestly, I am still adjusting to the my new Diamondclean Smartsonic

I have been using diamond clean for years and I credit my excellent oral care to it. I really don't use the coaching because I don't need to but what a great idea for those who do. This pink one matches my bathroom and makes me happy. My teeth just sparkle and contain zero plaque. Thank you Phillips for taking such good care of my teeth. This is the wisest investment one can make to ones general appearance and well being. Years ago I had dental assistants match crowns to the color of my teeth. I wish I would have requested whiter crowns. There is no better proof than that, PHILLIPS rocks.

I've had several electric toothbrushes; Oral B, & earlier versions of Philips'. This is not an "electric" toothbrush. Philips has created an "ELECTRONIC" toothbrush! You get feedback while you're brushing - for instance, it lets you know immediately if you're brushing too hard. You can program your brush for different levels of how hard you brush, as well as what you're trying to achieve - general cleaning, whitening, gum care, etc. And Philips has multiple brush heads to help you reach your oral care goals.
If you're on the fence about a new cordless electric toothbrush, get this Philips - that pitch about "use a brush like a dentist's" - this Philips has the small rotary head like Oral B, but Philips also has brushes behind as well. I had an Oral B before this, and the difference in performance and results is like night and day; I will be staying with Philips for life.

Philips Sonicare DiamondClean electric toothbrush. Simple. Stylish. Neat. Exceptional brushing.
I have been comparing Philips Sonicare DiamondClean to my other older Sonicare unit with uv light sanitizer and slightly newer competitiorGenius and manual c.360 for the past week (im not allowed to mentioned other brands in this review). And honestly, I’d prefer to use Sonicare DiamondClean at all times because it does the job so well. With such variety on the shelfs its hard to choose that perfect brush and trust into its efficiency.
And why do you ask I still use manual? No I don’t forget to charge my brushes, and Sonicare DiamondClean battery lasts for weeks, its that sonic zoom of a functioning toothbrush (even quite content zoom of my new Sonicare DiamondClean), still scares my dogs into barking fits. And if your dog is 100lbs and has a sonic boom of a bark, and you get up 5.30 am so you can walk said dogs for 1.5miles, you’d do anything in order not to wake up entire household. So if im quick and shut the door before my Velcro pets, I indulge!
This toothbrush is packaged and presented a fine tool should. Its quite stylish, fits great in my hand, not bulky at all or heavy, has quite zoom, the glass charged (ever so more convenient then my previous Sonicare charging stations), I like the color, girly girl that I am. But it also comes in black, silver, and white colors. The charging station consists of a metal ring into which what appears to be a glass is inserted. Glass can also be used for rinsing and not only charging.The brush also comes with a travel case that can hold a Sonicare and 2 replacement brushes. Because it’s a travel case, it has a usb port and you can charge Sonicare from portable charger or a laptop.
As soon as the Sonic care is touched, the menu lights up. The material of the handle is pleasant to the touch, I had a brushes that felt sticky or gummy, this one is just nonslip. My handle is powder pink with milky white led’s and chrome accents. All parts are easy to clean and to rinse, there are no deep grooves where dirt can build up, the glass charger is glass, and is dishwasher safe.
Cleaning modes are
Clean
For exceptional everyday clean, 2 minute standard cycle
White+
To remove surface stains, it adds extra time to whiten your front teeth
Deep Clean+
For an invigorating deep clean, extra time to be more thorough
Gum Health
Special attention to molars, extra time to massage your gums
And 3 intensity settings
• High
• Low
• Medium
The factory packaging included 3 types of toothbrush heads (Premium Gum Care brush, Premium White brush head). They have codes on the head, and I have to lookup what which is which, but I’ve chosen Premium Plaque C3 for my twice a day cleaning.
Cleaning is simple – when you attach a toothbrush head it automatically selects a cleaning mode. So far I have tried whitening (you can override the default mode by pushing the button under the power button before you turn the brush on) and stuck to Deep Clean. You can change the intensity of the cleaning by pushing the button under the power button while the brush is running, and there are three levels to choose from. Lastly, if you push too hard the bottom of the toothbrush will light up to let you know to ease up, which is impossible to see, by the way, if you are not in front of the mirror. After the cleaning cycle has completed the toothbrush will automatically turn off, or you can manual shut it down by pressing the power button. Warning – do NOT apply toothpaste and turn on the brush until its in place in your mouth, the toothpaste will be all over you and walls in fine white spray if you do!
Small toothbrush heads are easy fit for all types of mouths and is easily maneuvered, the buzz is not unpleasant. The results are Sonicare clean. My teeth feel cleaner, I never had to brush twice because they did not feel right. But this is consistent with my other Sonicare brush. As I have mentioned before, its been just little over 1 week of me using it and I cant say that results are more dramatic that my older Sonicare brush, nor did I use tong cleaning or gum massaging.

This model has a built in Bluetooth (and what tool does not now days? Even my meat smoker has a Bluetooth!) You can download optional App from Google play or Itunes. It promises that
“ With the Philips Sonicare app you can see where you’re brushing, navigate trouble spots, and get real-time guidance on the right pressure and brushing motion. All from the palm of your hand.”
Im sorry, but 1. Bluetooth kills my Samsung galaxy s7 battery and 2. There is no way im staring into my phone while brushing my teeth. Besides 3. Reviews on google play for the app is only 2.5 out of 5 *’s. I’ll install and use it when rating reaches 4+, otherwise it will just be another clutter app

Overall, this is an excellent new addition to Sonicare family of brushes, will appeal to all levels of dedicated followers of new and improved technology and will do a consistent remarkable job of teeth cleaning!

This product was free in exchange for my honest opinion.

While I did receive this as a free sample to review, I have used electric toothbrushes before. That said..This is amazing and really high tech. It looks nice on the counter, came ready for my first brush and no assembly required. Just plug it in, sit it in the nice little clear glass cup that is the charger and off you go.

I downloaded the Phillips Sonicare app from the Google play store, set my goal to whitening and it showed me exactly how to to do it. The toothbrush connects wirelessly to your phone via Bluetooth when you turn the app and the brush on. Then a little picture of a set of teeth shows up. As you start brushing, it shows you where you are brushing and where to go next to achieve best results. It is really cool. The brush handle lights up at the bottom if you are brushing too hard or using too much motion. Then, after you are done, the app tells you how you did. It tells you if you got all your teeth, if you had too much or not enough pressure, etc. And it will show you in 3-D. I really liked the fact that I could customize where I started brushing because it is set up to start on the lower right and I start on the lower left. You customize if you want to work on your gums, whitening, deep cleaning, the intensity of the brush, how long you brush.

This brush would be great for kids, too. They can see what they are missing AS THEY BRUSH! Plus you can control everything else.

The only negative I had is that the travel case does not close all the way when you the brush heads in with their caps on. So I took the off.

Brushing meet the 21st century!

I was very excited to receive a free sample of the Philips DiamondClean Smart to review. I have been using a Philips Sonicare for years, and I didn`t really expect there to be a significant improvement, but I was wrong. The DiamondClean is amazing! I tried using all three brush heads and cleaning setting methods. I could tell a difference between each one, but all three left my teeth feeling as clean as they do when I leave the dentist after a cleaning. I`ve never had another toothbrush system give me that effect. And maybe it is just a placebo effect, but I swear my teeth are already whiter a week later. I did use the app the first few times I brushed. It was helpful for timing and determining where I needed to brush better, but it isn`t really practical for me to use every day (I don`t usual have my phone handy when I`m getting ready for work or for bed). The base is very attractive (I have the blush pink color) and the travel case is very nice. In fact, I`m traveling at the moment, and love having the case, which allows me to bring multiple brush heads with me. The wireless charger is also a great plus. I highly recommend this responsive, attractive, and effective update from Philips. I don`t think I can very go back to an inferior brush!! - Melissa H.

Having used a Sonicare electric toothbrush for several years, I really did not expect this one to be that much different. Was I surprised! It was incredibly different and improved.

The toothbrush is a nice size and fits well in my hand. The handle has an illuminated display that indicates the four mode choices and the intensity level. It came with three different types of brush heads and a very nice hard shell travel case.

The instructions for set up and using it were easy to understand. I downloaded the app and sync`d my iPhone`s bluetooth with the toothbrush. I opened the app and followed the directions. The app provides a lot of feedback to help ensure I am brushing thoroughly. It shows areas where I missed and guides me back to those spots to brush again. It also indicates if I am using too much pressure or scrubbing too hard. There is a lot of information available in the app about my brushing habits. It also has a reminder of when to replace the brush heads. I was skeptical as to whether all of this information was necessary, but after using it for several weeks, I do feel that the feedback from the app is helping me to do a much better job keeping my teeth and gums clean.

The charger for this toothbrush is a glass. The toothbrush sits in the glass to charge but you can use the glass to rinse after brushing. I will say that the toothbrush and glass look very nice sitting on my counter. Overall, I am very impressed with the Philips DiamondClean Smart electric toothbrush. I really believe my oral health is improved by using this toothbrush.

I received the Philips DiamondClean Smart toothbrush for free to try out and give an honest review.

I have owned my fair share of electric toothbrushes over the years, but the Phillips Sonicare 9300 DiamondClean Smart toothbrush is best electric toothbrush I have ever used. The smart system includes a lightweight handle with three interchangeable brush heads, a charging glass and a travel case. I am in love with the pink pearl handle.

I've been extremely pleased with how easy it is to operate. Not only does this toothbrush does a great job cleaning your teeth, but also has whitening, gum health and deep cleaning features.

The rechargeable glass is practical and functional. I've never seen any thing like it before. Simply place the toothbrush brush in the glass and the handle charges. While the manual says the Li-Ion battery holds a charge for 14 days, I found the charge to weaken around day 12.

Nevertheless, I love my Phillips Sonicare 9300 DiamondClean Smart toothbrush! My teeth feels clean after every use. Since using my Phillips Sonicare 9300 DiamondClean Smart toothbrush, I find myself running my tongue across my teeth.

The Phillips Sonicare 9300 DiamondClean Smart toothbrush is a great investment.

I have been using my diamond clean smart Sonicare toothbrush for about 2 weeks now, and I am very happy with it. Let me start by saying that I did receive a free sample product for use prior to writing this review.

It has a ton of bells and whistles, some of which are great, and some of which you can use if you choose, or might be far more than you are looking for in an electric tooth brush.

If you are new to Sonicare or to electrical brushes it will take a few days to get used to the intensity of the brush, and learning to not launch your toothpaste across the bathroom when you turn it on.

Several of the features that I like are the app. It has many unique features that can be very helpful if you choose to use it.

I also like that the timing is different in the zones of your mouth according to what you are trying to achieve, whether it is whitening or gum health. Again, you don’t need to follow the recommended timings but following the recommendations will improve your brushing effectiveness.

I like that the unit detects the brush heads and matches the intensity to the brush head, but that you can change the intensity according to your comfort level. I also like that it indicates when I need a new brush head. I have had Sonicare tooth brushes in the past, and I was never quite sure when I needed to replace the brush heads. The brush heads are a little on the expensive side but I think they will be worth the cost based on the differences in my dental appearance and health that I noticed.

The intensity ring light is very helpful, and where it is located is brilliant, I can see in the bathroom mirror if I am brushing too hard or not. I do not always sense the change in the brush intensity or the sound change, so I like this feature, but I need to make sure I brush in front of the mirror to fully appreciate it.

I love the travel case, I am sure that my unit will be protected when I travel with it, although the USB aspect was a little confusing.

There are a couple of things that I didn’t particularly like about the unit.
The manual was a little hard to follow, for example, I couldn’t readily tell if my unit had a USB charger or not, even after looking at the box, I had to get the model number off the unit and carefully examine the case to see that my unit did not have this feature. I do think it’s a great Idea as I travel a lot for my job and would love to always take my brush with me when I am away for more than a few days.

It was a little difficult to tell which brush head was for what. Perhaps the brush head name could be printed on the brush?

The battery indicator is nice but when it starts blinking I am not sure if that means charge now, or you have one or two brushings left. The worst is when it dies mid brushing, but that is the same with any battery-operated device. The battery life has not been what I expected. With a 24 hour charge I would have gotten according to the instructions about a 14 day charge. I had to recharge the brush after 5 days of using it twice a day. As much as I like the fact that the brush charges in the cup, reducing the amount of stuff I need to keep on my bathroom sink, I am not certain that the inductive type of charge works well. My bathroom is a very busy place, and the brush is constantly moving in the glass and I am not sure it always has enough contact to charge. Also I try to keep the cup clean and dry after each use, but it often gets dirty and I am not sure how this affects the charge.

Another concern with the unit is that I have very large hands, and the unit just didn’t seem to fit. I was also afraid of dropping the unit, as it seemed like it would probably cause damage. Perhaps rubberized grips or a clear indication on how and where to hold the unit would be very helpful and may quell some concerns of droppage. I also asked a family member with really small hands to hold the unit and she wasn’t quite sure where the best place to hold it was. Both of our fingers gravitated to the buttons. I found myself inadvertently changing intensity and shutting the unit off by mistake.

All in all, I was impressed by the diamond clean smart. After using it for a few days I could sense the difference in my teeth, I could feel the difference in the cleanliness vs my current electric brush and brushing by hand. My teeth were visibly whiter and there was an immediate improvement in my gum health.

I would recommend the unit to anyone who wanted to upgrade an existing Sonicare or go from a manual brush to an electric brush.

I was lucky enough to receive this product for free in exchange for my unbiased review.

I have been using a Sonicare electric toothbrush for over 8 years now and have loved it. This toothbrush, however, blows my old one out of the water. At first, I thought that there wouldn`t be anything a newer toothbrush could offer that I wasn`t already getting from my old Sonicare. I was wrong.

This product comes with the ability to connect via Bluetooth to the app on your phone, which at first sounded like it would be more of a hindrance than an asset. I also thought it made the product seem pretentious. The handle also has the ability to recognize the type of brush head attached. All of this new technology made me worry that it would be wasting a lot of my time and probably be glitchy. But I had no such issues.

The product manual mentioned some models have a USB charging cable on the travel case, which would be nice, but apparently, this model does not include. The travel case itself is nice as it is sturdy and molded to protect your investment. My previous model Sonicare had a flimsy cloth case and once got accidentally turned on while I was traveling.

While the charging stand and glass look aesthetically pleasing, I would rather have just had a stand alone. I understand the glass has a separate purpose of using for rinsing, but for me, it is just one more thing I have to keep clean.

This product can use 4 different types of brush heads but came with only 3 types: Premium Plaque Control, Premium Gum Care, and Premium White. (The other one is the Tongue Care, which I would not use anyway, as I use a metal scraper and would not want to change.) So far I have used all 3 heads a least 3 times, and I am very impressed. My teeth have never felt cleaner, except when I actually have a dental hygienist clean them. I like that the app can tell me in real time, along with the vibrational changes on the handle itself, when I am using improper pressure or too much movement. I also like that the app shows you exactly where to brush and for how long. With my old Sonicare, I used to count to estimate how much time I had left in each quadrant. No more counting needed!

I also feel that it`s easy for me to tune out when I`m brushing my teeth and not pay attention to proper technique. With this handle and app combo, it keeps me awake and alert, which is a nice way to help me wake up in the mornings!

I do wish that there was an allotment for the actual bite side (top) of the teeth. I end up just trying to squeeze that in between the insides and outsides. I also know of some Sonicare models that include a method to sanitize the brush heads. With the expense that this model costs, I`m surprised that was not included. Overall, however, I think the handle is comfortable and well constructed, as I have come to expect from Sonicare. I like that there are 4 different cleaning modes on the handle (clean, White, gum health, and deep clean) along with 3 different intensities to choose from. When you first attach a brush head, these settings are chosen for you, but you can easily adjust them as you like.

Then there`s the app itself. It has all of the bells and whistles I could think of to help me get the most out of by brushing experience. It has reminders, real-time tracking of your brushing activity as well as the brush head performance, even links to purchase new brush heads when the time comes. You can customize the goals and the trouble areas in your mouth. I`m pretty impressed with the technology and as a self-proclaimed techie, that`s not easy to get out of me.

This is a first-rate product, but it does come with a first-rate price. And the brush heads have their own new technology with them so they are a bit pricey as well. However, if you have the money, this is a solid investment and your dentist will probably be proud.

I received a free sample of this toothbrush, and am thrilled that I did! I have used many electric toothbrushes and this one is by far the best I have used. It is high quality, easy to operate, and all of the instructions were easy to read. After using it for a week, I noticed my teeth were definitely cleaner and whiter than before. I love the different options in brushing and brush heads. I used both the whitening one as well as the one for gum care.

The toothbrush itself seemed to work far better than my previous Sonicare toothbrush and had many more features. I love the 20 second brushing intervals better than the 30 seconds that my previous brush offered. This allowed more time for me to focus on each area. The pressure sensor was amazing as well! I hadn`t previously realized that I was pushing too hard while brushing.

One of the best features of this toothbrush is the connection to the Philips Sonicare app. This app will tell you if you have not spent enough time in one area of your mouth so you can go back over it. It also tells you if you are moving the brush too quickly and tracks brushing, flossing, and tongue care. This is an amazing feature for children because they can see, on a screen, where they could do better. I wish this was available when my children were younger!

There isn`t anything I would change about this toothbrush and would recommend it to anyone!

Overall, I loved this toothbrush but the bluetooth feature with smart sensors is a little much. I did receive a free sample to use for this review.

Amazing points of this brush: 4 cleaning modes, 3 intensity settings (some people have a hard time adjusting to this type of brush), 3 smart brush heads, charging glass, and a 14 day battery. Brush definitely holds a great charge! I liked being able to choose which brush head I wanted to use. Very easy to use and teeth and gums look and feel much cleaner. The charging glass is super easy to use and helps keep your countertop clean.

I thought the bluetooth technology and corresponding app was a bit much. I don't really need to check my phone to see how I did brushing! However, this could be a great tool for those who enjoy having their phone nearby 24/7.

Before trying this toothbrush, I thought, “How great can it be? It’s just a toothbrush after all”. I was wrong. I received a free sample of this toothbrush, and these were my first impressions: Very high quality. I got the pink color, it’s a really nice dusty matte pink. The different light-up modes on the brush itself look very modern and nice. The charging glass is very elegant and high quality.
Functionality: This toothbrush comes with an App that shows you how you’re brushing. This blew me away. It shows you where to brush, and while you’re doing it, the brush knows whether you’re brushing the inside or outside of your teeth, if you’re applying too much pressure, and if you’re using an incorrect motion. The App shows you when you need to go lighter/slower/etc. This is brilliant, however for someone like me who isn’t attached to their phone, I probably won’t be using the app when I go in the bathroom to brush my teeth. There are also challenges you can set for yourself on the app and track your progress. The app also alerts you when it’s time to change the brush head.
The brush recognizes when you snap on the different brush heads (clean, gum care, white) and indicates the setting by lighting up the corresponding brush mode.
Of course, the actual brushing is fantastic. My teeth feel super clean, like I just left the dentist when I use any of the modes.
Overall: This toothbrush is top of the line. It’s definitely a “smart toothbrush”, and the added experience of using the app is something new and interesting. The overall look and feel of the brush, heads, and charging glass are very high quality. I would recommend this to anyone looking for the optimal brushing experience.

My prior Sonicare Diamond Tooth Brush was able to be charged in the travel case. With my new Sonicare Diamond Tooth Brush you can not charge the tooth brush in the travel case. Therefore, beside the travel case you must also bring the charge when traveling. That is extra space and extra weight. Give me a traveling case that I can charge my tooth brush in.

Product recommended by Dentist. Easy to use. Have had problems with app showing all areas brush. I maybe brushing longer which is negatively impacting battery life

I misplaced my tooth brush when transporting it back and forth to my camper and home. I used the opportunity to upgrade to a newer model. I can tell a big difference in the newer one when compared to the old one. It feels even more like I just got my teeth cleaned at the dentists.

I absolutely LOVE this toothbrush... until it stops working correctly. I have a diamond clean from 2013 that still works perfectly, however, the newer designs have a design flaw. I bought one in 2016 and one in 2017 and they have both developed a very loose base where you attach the brush head making for a very loud and ineffective brushing experience. Attached is an image comparing my brush from 2013 (white) to my brush from 2016 (pink)- you can clearly see how defective the product is. I had raved about the diamond clean to my friends and they are experiencing the same issues. Considering the price of the diamond clean, I should not have to be repurchasing this brush every 2-3 years. Very disappointed in Sonicare's warranty/replacement policy. If they fixed this issue the brush would be 10/10.

The electric toothbrush leaves your teeth feeling like you left the dentist office after a cleaning! Great product and the app is easy to use. Cleans better than the less expensive Sonicare. You can feel the difference!

I lovefthe feature of syncing with my phone.
Love the charger.
I find I get an excessive amount of “spray “ all over my sink, mirror and faucet when I brush. I have to clean up with paper towels.

I absolutely love the different intensities as well as the different modes to choose from, the downside is that the sensor for the head doesn’t always register movement when looking at progress made on the app.

Cleans teeth great, but this new diamond clean is very loud compared to previous models.

Love love the clean...dislike the base as I feel it's a balancing act I don't have time for in the morning as I'm rushing off to work

I have been a Sonicare user for several years now. Before using the Diamond Clean Smart 9300, I owned its predecessor – the Diamond Clean. I received a free sample of the Diamond Clean Smart 9300 in exchange for my honest opinion.

This toothbrush is a step forward in the right direction for Sonicare. The Diamond Clean Smart has four cleaning modes and connects to the Sonicare app through Bluetooth. It has a pressure sensor on the bottom which, when used along with the app, allows such feedback as when you are brushing too hard or using too much movement when brushing. Having come from a similar model, I still love how well this toothbrush works. It leaves your teeth clean and effectively removes plaque. Being able to control intensity is a huge bonus.

I do enjoy the smart features. Setting goals and tracking your progress through the app is quite useful and good reminder to look after one’s dental health. However, there are issues. When brushing while connected to the app, often times the app does not reflect that you are brushing the indicated quadrant when you indeed are. I attribute this to the sensor on the handle not being as sensitive as it would need to be in order to appropriately convey the info to the app. Other than this, I have no other qualms.

I would wholeheartedly recommend this toothbrush. It is an essential tool for good oral higiene.

Note: I received a free sample in exchange for my honest review

Overall, I think this is a really great product. It looks good, feels good in the hand and def. does a great job of cleaning your teeth. My one issue with it is that it just feels more complicated than I need toothbrushing to be. It has a lot of bells and whistles, and many of them are just more than I need.

I do like that it has multiple modes for different types of cleaning, but I don't want to have to juggle and keep track of three different brush heads. I also find the timer feature (the toothbrush pauses briefly every 30 seconds to let you know to move to the next section of your teeth) a little distracting. I would prefer it this was a blinking light or a sound rather than a pause in the action.

My favorite feature is the pressure sensor that lets you know if you are pushing down too hard. I definitely do that a lot and this is helping me retrain myself to be gentler on those pearly whites.

All in all, this is an effective, high-quality product. I will probably stick with my mid-range Sonicare toothbrush, but this is a great choice for someone who loves gadgets and wants all the bells and whistles.

for the first year i had this, it was fine, and my dentist said it was helping a lot with my gum, but after the first year, it rarely connects to the same iphone 6.

I really want to give it a high score, since it looks so lovely, but the quality really fails me, I tried two and they both have something problematic.
I had one that I really liked and functioned very well, but unfortunately the power button on the handle went wrong in the first month of use (didn't drop it down or press it hard). BestBuy exchanged another new one for me, BUT it is not as sensitive as the last one and does not respond to the app sometimes. And the pressure sensor is REALLY not responding when brushing (I tested it on my palm and it can work just not work well when brush teeth). The second toothbrush is just so insensitive and the light doesn't even flash sometimes when uplift the handle (the first one does). I don't want to try to exchange another time, because it doesn't help at all.

I have owned 2 diamond clean. The older version is much more durable than this one. I am still using the old one, but this one is not functioning well now.
