Customer Ratings & Reviews

The Philips Sonicare DiamondClean Smart 9300 Rechargeable Electric Toothbrush is a high-quality electric toothbrush that is packed with features that have really improved my oral health. In the past, I used to rush through brushing in an attempt to just get it over with which is obviously not the best way to maintain healthy teeth and gums. I’ve never had a cavity before so I figured I was doing good enough, but this Philips Sonicare Smart 9300 toothbrush has really shown me that I can be doing a much better job and I have really noticed the results by taking my time and following along with the app for a much more effective cleaning experience. The microchip in the brush heads allow the toothbrush to send data directly to my phone for personalized feedback and coaching during each brushing session. I had a lot to work on the first few times I used this new toothbrush but over time, I have gotten more used to the proper way to brush and I feel like it has helped improve my oral health tremendously. I don’t know if it’s all just in my head but my teeth just seem to look and feel so much better than they did after brushing in the past with my old electric toothbrush. Either way, I know my teeth are well taken care of now. One of the other cool things I really like about this Philips Sonicare Smart 9300 toothbrush is the charging glass. It is very stylish and comes in handy for rinsing while also effortlessly charging the toothbrush. The travel case that comes in the package is also a very nice feature since it makes it easy to transport the toothbrush and brush heads when travelling. Overall, the Philips Sonicare DiamondClean Smart 9300 Rechargeable Electric Toothbrush is great high-quality electric toothbrush and I highly recommend it!

This is definitely the fanciest toothbrush I've ever used. Pairing a toothbrush to my phone seems crazy. The real benefit to it though, is to help you develop better brushing habits. Of course that still requires some commitment from you, but if you're brushing regularly, but still getting cavities, this may get you on the right track. The catch is, you actually need the app open on your phone when starting a brushing session. The benefit to this is that it will tell you which area to brush, and will keep track of areas you have brushed. This helps with making sure you haven't missed anywhere. Once you've learned the pattern, you can go without the app, and just learn to switch areas when the brush momentarily pauses. It will double pause (if I remember correctly) if you are pressing too hard as well, so it also helps coach you with the appropriate amount of pressure. Once your phone is in range of the toothbrush, it will sync your brushing sessions, but it doesn't keep track of the areas your brushed, but it does track time and overall pressure. If you're really dedicated, it has some other features, such as adding areas of plaque buildup, bleeding areas, potential cavities, and gum recession. The only thing I wish it had was some gentle nudges to brush if I missed/skipped brushing, flossing, etc... It comes with a nice solid glass that you can use for holding the toothbrush, and holds the charger under it, so the toothbrush can charge while in the cup. This also means you could use the cup for rinsing your mouth too (if only I could remember to put it in the dishwasher). The battery is not replaceable. As a matter of fact, they have instructions for removing the battery for recycling, and it involves permanently breaking the bottom of the toothbrush to remove the battery. Planned obsolescence and I don't like it.

I’ve used the basic Sonicare toothbrushes for many years. They have been reliable and long lasting while also being good at what they are made for - brushing teeth. This 9300 series brush adds some genuinely useful smart features while being a more premium product overall than the basic Sonicare brushes I have used in the past. In the box you will find the brush with two heads, a travel case, and a customizable charging “cup”. You can place the brush in the cup or customize it to be more like a stand. The cup/stand piece is washable to keep it clean. The travel case is very premium feeling. The actual brushing experience is exactly as I expected from being accustomed to previous Sonicare brushes. The sonic vibration works just the same and your teeth end up feeling very thoroughly cleaned. The real significant features with this toothbrush come with the Bluetooth and app functionality. I downloaded the Sonicare app and my phone immediately detected the brush. Here, you can keep track of how often and how long you brush, and there is also a clean feature where you can see which teeth you may have missed. This is genuinely useful, as it keeps you on track to brush evenly throughout. It also tells you if you’re moving too fast or putting too much pressure on the teeth. Overall the smart features are easy to use and are genuinely useful, and certainly can help a person maintain better dental health.

Great toothbrush. Has many setting for a clean brush.

Toothbrush is great. Wish the carrying case included charging as in previous versions.

The brush died after 2 years. The button seemed to need to be pressed a couple of times before turning on for about a week. Then it just died. For the amount of money I spent on this my toothbrush should last at least 5 yrs. Very upset bc this was an investment gone to waste.
