Philips Sonicare DiamondClean Prestige 9900, Rechargeable Toothbrush with SenseIQ, Pink, HX9990/13

[This review was collected as part of a promotion.] This electric toothbrush holds its charge, has a terrific recharging travel case, and has seamless buttons. It also automatically turns off after 2 minutes.

[This review was collected as part of a promotion.] 3 speed vibration, softer than what it used to be Much better than Oral B

[This review was collected as part of a promotion.] I like the toothbrush since it makes my teeth feel cleaner Everytime I brush. I do wish the app showed individual teeth cleaning and not just a portion of my jaw that's cleaned. This way I can see which teeth I'm not cleaning as well. Other than that, great toothbrush.

[This review was collected as part of a promotion.] Love the toothbrush, but the app is inconsistent. The app feedback does not pick up on seemingly the same areas. Very annoying. I bought this new model hoping to solve the same problem with my previous Sonicare. It did not. Years ago, I rarely had this problem. Now, I am shock when it works correctly. Very disappointing considering me upgrading at a considerable cost.

It's been a week and still no warranty info. I prefer a button to select speed and a hardwire charger instead of the charger using phone charger Delivery of item was ok

[This review was collected as part of a promotion.] Love the toothbrush and feature of too much movement and pressure notification. I wish the app was more accurate on re-brushing missed areas

[This review was collected as part of a promotion.] I would have given a 5 Star, however, when brushing the app does not recognize me brushing on some quartering and request touch ups. Sometimes it will recognize all areas and say complete clean. I am not sure if it is a flaw in the AI Brush or the App. I ignore it when it does it because I am fully aware when brushing all my teeth. I had this toothbrush in Champagne color stolen by TSA in August and turned around and purchased the Black color one to replace it and remind me when I travel not to trust TSA. So in the length of time using this brush will include both brushes.

[This review was collected as part of a promotion.] I like the toothbrush and I'm still learning how to use it more efficiently and effectively

[This review was collected as part of a promotion.] I love this toothbrush. I deducted 2 stars for the high price, the durability (my old one broke after 4 years), and lack of repair capability (tried to get the broken one repaired, but Philips said that wasn't possible). With those caveats, I love the way it cleans my teeth. When it's running, I believe it's the best on the market. That's why I keep buying even with the high price.

[This review was collected as part of a promotion.] This was my 3 or 4th Sonicare toothbrush, so I do love the brand and the functionality of the sonic brush design/process. However, the newer brushes rely too much on the App for a feeling of ease of use. With this brush, you need to use the App to adjust too many settings, whereas the previous models allow for quick and easy adjustment right on the brush handle. As the App tends to fall out of sync with this brush head and seems to require you to bring the iPhone or other device housing the App near to your brush handle for connection each time, it is a non-starter for me. I returned this model and purchased one of the older models to replace the one that had stopped working. Lession learned: new technology is not always better or more efficient.
