Customer Ratings & Reviews

Really like how this works compared to my last Sonicare toothbrush.

Great toothbrush. It seems to vibrate faster than my OralB, but that was getting old, so… But I would recommend as my teeth and gums feel great and I don’t remember the other having that effect.

Will continue to use the product I need to find the tongue scrapper tip

Amazing toothbrush. Upgraded and am very pleased with it

So much better than the original sonicare the cup and charging platform or so much easier to clean

Best toothbrush out there. Amazing app interface. Highly recommend

This toothbrush is cheap and loud. In addition to the sonic noise,there is a loud motor noise. My last Sonic from 10 years ago does not make that additional noise. Quality of Philips has obviously diminished. I would not recommend this item to anyone. Further, I have spent over 1 hour talking to people from around the world, and I continue to get conflicting information. I hope I am able to get my money back for this piece of trash.

I don't know why I waited so long to get one of these.

Best home use oral cleansing, whitening, brushing!

After my previous Philips Sonicare toothbrush bit the dust after almost 6 years of service, I tried out a couple of other brands that had some fancy features and looks. However, after 6 months of trying, I got back to Philips again. This time I got my hands on the top of the line model, the DiamondClean 9300. And after using it for more than a week now, all I can say is there’s a reason Philips Sonicare are so popular. The DiamondClean 9300 is not cheap, and that’s because instead of being just another electric toothbrush, this is actually a “system”. I really liked the charging part - there’s the usual wireless charging puck that needs another “fitting” to accommodate the brush. A small plastic stand helps do that. However, in the box there’s a rinse glass that doubles as a brush holder and a charger, while still being able to be used for mouthwash. Along with the charging stuff, the package also includes a travel case that holds the brush body together with 2 brush heads. The case is slick, looks nice, but not the most hardy. Especially it opens up very easily even though it is held by magnets. Also it has no other functionality, unlike an expensive model that has charging capability. Coming back to the actual brush itself - 2 brush heads (A3 and C3) come with the kit, with a life of 3 months each. The A3 is the all-rounder here, while the C3 foregoes the gum care capability to deliver a cheaper option. Both heads worked as it should be, and cleaned my tooth with good precision without being too hard. The build-in pressure sensor, which has a visible indicator as well, helped make sure I was not trying too hard and making things worse. Also, being a smart toothbrush with Bluetooth connectivity, real time feedback can be had via the Sonicare app. The app itself is simple to use and quite helpful in keeping track of brushing routines, but the necessity of an account is cumbersome. There are 4 modes of operation: Clean, White+, Gum health, and Deep clean+. I typically use the Clean mode everyday, with occasional use of the Gum health mode. The Deep clean+ felt a bit too overpowering for my teeth, even though for every mode there are 3 levels of intensity to play around with. From my experience, for regular users, one or the other mode will definitely work. Overall, the Philips Sonicare DiamondClean Smart 9300 seems to be a smart investment for those looking for a high-tech toothbrush to enhance their dental hygiene routine, with the caveat that it may be more costly than other options.

This product was both on June 1st of 2025 and the motor broke from Normal use on September 18th 2025 which is unacceptable for a product with a price of 200$!

I enjoy this brush system so far. But why am I giving it 4 stars. My main gripe with this is that it is not the best for traveling. This does not come with the charging case that they have. The charger itself is fairly heavy. If it at least has maybe a travel bag that you could store everything in to take with you, or the charging case, then I would give it a 5 star. the basic directions also say to use 1 of 3 brush tips and yet this only came with 2. The third was a tongue brush. This is not even provided on the back of the other brushes. Those are not to big of issues, as this comes with a case that holds the unit and 2 brush heads and it last a good amount of time. I do like that it does wireless charging and seems pretty easy to charge. You have 2 options, either use a cup and you just put the unit in the cup, or it has a stand. I have been using the cup myself. It has a couple different settings and speeds that you can choose from to perform different things such as clean and deep clean mode, white mode and gum health. You can also sync to a phone via their app and have it monitor for you. Most of the time even on low settings I find that these usually hurt and I end up using like a regular brush. So far this model does not hurt and when I am done using it, my mouth feels way cleaner. Overall a great product and easy to use. Leaves your mouth feeling cleaned.

i received this Sonicare on 7/31, and am writing this today 8/22. The toothbrush shorts out and is clearly faulty. I have owned approx 5 Sonicare toothbrushes and am a fan of the product, despite this faulty one. Best buy wont take it back or replace it as i am outside 2 weeks. apparently i need to buy an annual membership so i get an extension of an additional 6 weeks. DO YOURSELF A FAVOR - get it direct, or through Amazon.

Bought sonicare toothbrushes for years and always loved them, however this one never worked. Bought my wife this as part of her birthday present and she was happy to open it at least.

Received wrong item. Could not return at store. Had to visit store several times before store accepted the return, because it was a wrong item altogether.

To start, there is nothing I dislike about this toothbrush, as a standalone product it's pretty good. however, there are a few things that competitors have that I like better. Let's start with the accessories - this one really stands out. The ability to charge it in the provided glass is a great idea and keeps your area looking clean and neat. Others, particularly ones that are black, can get pretty dirty with residual toothpaste build-up on the charging stand Aesthetics and feel - Again this is a really nice looking toothbrush and it fits the hand really well and has a pretty good balance- for me personally, I like a round head brush as compared to the oval shape of this one but that really is more of a personal opinion based on how tight my mouth is at the back molars. As far as cleaning/function - it seems to do a good job, at least as far as I can tell. I'm not a dentist and they never seem to be happy with the amount of cleaning you do 😊 but that being said it does seem to clean the same as others on the market. I would have liked to see a few more cleaning options but the ones that are there will suffice for most people. Also, it comes with two different brush heads, and I could not tell any real difference between the two. The vibe and auto shut-off let you know where you are in the bush cycle Connecting and app - I did not have any issues with connections either in setup or subsequent connection - it worked flawlessly. As for the app, there are some nice features, like it tracks the number of uses on the brush head - even if you don't connect to the app when you brush. It also has some nice guides to help you clean however the main one takes 4 mins and the brush auto shuts off after two. Overall this is probably the weakest part of my experience. Charging - I used this brush for a week without charge and had no problems also it easily charges overnight. I'm sure that will change over time but no indication that there would be any issues if you simply drop it in the charge glass when you are done - it should be ready for the next brushing cycle. Overall - it's there nothing major to complain about. There are a few areas that could use improvement but nothing that is a showstopper for me. If it had a differently shaped head, I might be pressed to find something I didn't like and that is just a personal preference.

This toothbrush is simple to setup, with or without the app. There are two options for the charging stand whether to have the brush sit in a cup or straight up on a stand. The battery supposedly lasts for 28 brushing cycles. I have not hit that point yet, but I can definitely say I charged it the night I opened it and then left on vacation. The brush is working great, still on the first charge. With the app open, my phone and brush instantly paired. The app has a map of the mouth with a timer to show how much time needs to be spent in each area. I really like that they have the mouth divided into six areas instead of four like my prior brushes. 20 seconds in each area is easier for me to handle. As a really impatient person, I get bored in 30 seconds. The shorter periods obviously go by faster. While the app is not required to be open, the brush records brushing sessions and seamlessly syncs with the app whenever I want to see how I am doing. I purposely waited three days to sync the data. It took a few seconds to update and show me my brushing data. The brush has a 14 day build up feature for first time users so they can get used to the power. I chose to skip that and try the full experience so I had enough time to write my review. To say the least, this brush is powerful! But, my teeth have never been cleaner other than the moment I walk out of the dentist’s office. They look and feel great! I have a permanent retainer that loves to catch bits and pieces of food. This brush is easily cleaning it where my manual brushes struggle. Overall, I finish brushing and my mouth feels amazing! At the moment, my only complaint is that the included travel case does not close completely. They probably made it that way to let a wet brush dry out, but it also means any dust or dirt from my carryon bag can easily get into the case. I would prefer a tight seal to keep the brush clean. Otherwise, I am really happy. I would definitely recommend this to a friend.

This Philips Sonicare 9300 DiamondClean Smart is really pretty amazing. Easy to use with a helpful app that you will find you need more than you realize. It is build well and balances nicely in your hand. The various brush heads cover all your needs and are easy to swap out. And I might ad easy to find replacements for. I really like the charging base. Makes it easy to keep it charged. Being able to place the brush right in the included glass and just let it do its thing without needing to fumble with an actual plug is great. The power is of course adjustable. The top power level is incredibly powerful. Almost too much so. I mentioned the app before. Now you might think you don’t need an app to help you brush. But to get the best use out of the 9300 the app is important. It will communicate with the brush and give you details on how to best use each brush head. It will even give you slight movement in the brush handle when it’s time to move to the next section. Pretty ingenious if you ask me. Overall this is not just an electric toothbrush, it’s really an overall health care system for your teeth.

The Philips Sonicare smart tooth brush does a great job helping get your teeth extra clean. You can choose from a number of calling modes; clean, whitening, gum health and deep clean +. Some of the cleaning modes will have a longer brush timer, but the standard clean is two min. Unlike other my current electric toothbrush, I like how the Sonicare breaks up the timer in to six segments vs only four. This ensures you get adequate time on the front of your teeth. The brush works on its own but you get more out of your brushing while using the app. The app helps with set up and provides video tips for brushing. To you must open up the app and get to the brushing mode prior to turning on your toothbrush. Once that is done, there is a visual that aids you through the brushing process and helps you focus on correct angles and pressure. There are sensors in the brush head that helps facilitate this feature. I think the visual does a good job with instant feedback so you know you are getting a good clean in all areas. As a bonus at the end of the brushing session, if you happened to not do a good job in particular segments, the app will ask if you want to do touch ups in those areas. A truly remarkable feature to get you to learn how to brush properly. The app will give you stats of your brushing history. It will sync with the brushing activity you have done without the app on, however it will not provide the details in your brushing. I can see that brushing with the app on day in and day out could be a bit of a hassle, but time will tell. Perhaps scaling back after you get use to it would be an option and you can see if you are still doing a good job from time to time. If you notice you are not doing a good job, that could be an indicator. The packages comes with the handle, two brush heads, a travel case, a charging stand and a charging option in a rinse glass? I’ll be honest, I don’t see the rational with being able to charge the brush handle in the glass. If there is one complaint I have with this package, it is the travel case. The clasps is really weak. Barely holds the weight of the brush handle. Not very secure. Other than that, I think it’s a solid product and would recommend it.

I never knew I needed a toothbrush with an app, but this one has it. The app guides you how fast to move the brush, shows which part of your mouth to use it on, and monitors how much pressure to apply. All very useful as I discovered I was originally moving the brush head around too quickly. The app also lets you set brushing goals, and gives you brushing factoids. I didn't find the goals or factoids useful. You can use the toothbrush without the app as well. A manual toothbrush is no match for this. The Sonicare leaves my mouth feeling cleaner, especially in the back side of my mouth where there’s little room to actively move a manual brush. It’s harder to compare, however, whether this is significantly better or not than rotating head electric brushes. One of the touted benefits is that sonic technology forces liquid in between teeth, thereby reducing plaque better. Search hard enough on the web and you’ll find conflicting conclusions on this claim. All of them, however, do a good job on gingivitis. I also have a Sonicare that’s not a DiamondClean series like this one. It seems to take a little more effort to get my teeth as clean as the DiamondClean, even when using the same head. Other features may help you decide if this is the right brush for you: - Sonic technology is quieter than a rotating brush head. I had dropped my previous Sonicare brush and something internal came loose. Though the brush still worked, it rattled and annoyed me to no end. I was very glad to get this replacement. - The brush head is in a long form and designed to brush by following the gum lines. I like that better than needing to pay attention to each tooth individually. - I like using the app because it makes sure I’ve properly cleaned each section of my mouth. It also warns me if I’m applying too much pressure. - The box comes with a travel case and a glass cup. The cup can hold your toothbrush on your countertop, and allows the charger to charge your brush.
