Doesn’t need the app
||Posted . Owned for 5 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Bought this to replace my moms unit that finally stopped holding a charge after about 3-4 years of use. The app feature stuff is annoying and pretty dumb if you ask me, but it doesn’t interfere with the actual device if you don’t want to use it.

DiamondClean Never Fails To Impress!

It is absolutely clean feeling and will continue to use DiamondClean products forever. People will not understand the value of a brush like this until they buy it.

Awesome toothbrush
||Posted . Owned for less than 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Bought this to replace a older Sonicare that finally died after 5+ years. This one is modern with new technology that makes it cool. My only gripe is that the case doesn’t have the charger built in anymore and is just a case now.

Quality Sonicare!
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Bought this for my wife to replace a sonicare unit she has had for years. Great quality, and the color is pretty cool. Charging glass is really cool, and a upgrade from the normal charging dock.

Good investment
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.It’s expensive but it does a good job at making your teeth feel clean. Has helped my gum health a lot as well. I’d purchase again though I don’t use the app, it’s finicky and I’m too forgetful anyway.

Best of the best!

Many features and the accessories are great — love the charging cup and WiFi app reminds you when and how to properly brush.

Skip this. Poor quality, mediocre features.
||Posted . Owned for 1 year when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I'd owned a lot of cheaper sonicare toothbrushes over the years. They had all ended up dying a year or two in to use. I decided to try an upgrade option to see if the more expensive brushes last longer and are more resilient. Unfortunately, they are not. This toothbrush died after about 15 months, which is crazy given the price. While it worked, it was an ok toothbrush. The smart features are ok -- they make you aware of how much time you're spending on the front/back of each area of your mouth. But they're pretty limited, if there's one tooth you always miss on one side, the software isn't going to figure that out. Overall: Skip this. Poor quality, mediocre features.

Posted .Hi there, Dan
Thanks for taking the time to write us a review here. We're very sorry to hear you didn't have such a positive experience using our Sonicare toothbrushes. This must be quite inconvenient for you. We would advise you to fully charge the appliance for 24 hours using the different chargers that came with your purchase while also trying other power outlets around your house and making sure there aren't any metallic surfaces interrupting this process. Also, please make sure your mobile phone and your app are updated to the latest version.
Hope that helps, but if you have any further questions, please feel free to get in touch via social media. We’re available 24/7 on Facebook and Twitter. Alternatively, you can reach out to us via the contact page on our website. One of our colleagues will then try their best to help you further.
Hope to speak to you soon!
Kind regards,
Philips Consumer Care

Not the best
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.First one I bought wouldn’t charge at all no matter what outlet I used. Had to exchange for a new one. But the Plaque Care whatever the cheaper one is I got, has worked for months way longer and better. Thought I needed an upgrade, thought wrong. Bottom line - not worth all the bells and whistles.

Great electronic toothbrush for a first-timer
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This is my first electronic toothbrush ever and I chose this because Sonicare is one of the leading brands in the market. Do I use the app every time I brush my teeth? No, because I don’t carry my phone with me everywhere I go. Otherwise, my teeth have remained cavity-free since I started using it and I replace my toothbrush heads every 3-4 months.
