Great toothbrush!
[This review was collected as part of a promotion.] This toothbrush is terrific. My teeth are not only feeling cleaner but are whiter. It’s easy to use and by syncing it to my phone, I am able to monitor my brushing methods and make improvements. Worth the purchase.

Great product
[This review was collected as part of a promotion.] I’ve been using Sonicare for over 30 years. I’m impressed. My dentist is impressed. It is a quality product however, if anything goes wrong it is quickly resolved

This model is a dud
I've been buying Sonicare brushes for decades and this will likely be my last one. In less than 1 year of ownership, I've sent this brush in for warranty replacement 3 times. Warranty replacement is nice but I'd rather not spend hundreds on a toothbrush that breaks quarterly.

I don't like charging station for travel
[This review was collected as part of a promotion.] I like the toothbrush itself. I do NOT like the charging station as I find it is cumbersome to pack up and take with me when I travel.

Great features, questionable build quality.
Broke within the 1st month of use, just stopped turning on despite being fully charged. They honored their warranty but I'm worried how long the new one will last.

Great toothbrush
[This review was collected as part of a promotion.] A great toothbrush, took a little getting used to but because of the vibration, but once I did I loved it, does a great job cleaning and my teeth feel really good.

Good product encouraged by my dentist, but…
[This review was collected as part of a promotion.] Purchased the DiamondClean Smart 9300 as replacement to older DiamondClean product (battery wore out) and hoping to continue not having cavities. I wish for more flexibility in selecting power settings when using the 'Deep Clean+' mode, the intensity automatically defaults to low, and I have been unable to change it, despite following the user manual. I find the pressure sensor and BrushPacer guidance very helpful, however, I find the feature “When brushing with the Philips Sonicare app in 'Deep Clean+' mode, the brushing time will be 2 minutes when connected to the app and 3 minutes when not connected to the app.” tempting me to not use the app.

Not happy - liked my old one a lot
[This review was collected as part of a promotion.] I made a mistake buying this handle. Liked my old one that died and you do not have it available any longer. The 20 second interval is messing up my routine. The recommended brush pattern is not my cup of tea. Also the charging stand has no place for brushes. I take the brush off the handle every time I finish brushing.

Great brush to remove plaque
[This review was collected as part of a promotion.] It’s keeping the tartar off and I am getting better check ups when I go to the dentist for cleaning

I would it buy it again
[This review was collected as part of a promotion.] I do take a very good care of the brush and wipe it diligently after each use. It is great for a month or so, afterwards the blower button gets clogged and has to re in it under water for a while then it may or may not work

Great features
[This review was collected as part of a promotion.] I think this toothbrush is an excellent deal. It has 4 different controls on it so it even has gum settings.

Best Results!
[This review was collected as part of a promotion.] The best toothbrush for cleaning and gum care. It’s the one my dentist recommended. I like that I can use it in the shower. Only negative is the mechanism that hold the toothbrush tends to wear out quickly. Philips needs to make it more durable.

I'm having problems with balky recharging.
[This review was collected as part of a promotion.] I'm having problems with balky recharging. I've had this type of toothbrush for YEARS. So I know how they work. But this one has been losing its charge more quickly than I'm used to and taking considerably longer than before to recharge. Did you Philips change the battery tech being used?

Too slippery
Need a softer head option and I find the body of the toothbrush slippery when using it.
