[This review was collected as part of a promotion.] I like the brush size and shape. The gum care brush is my go too. I went from oral B to Philips. Did not like the round oral B brush.

Just laid my second one of these toothbrushes to rest after a little over a year of working. It's a nice toothbrush when it's working, but one day it just stops functioning for no reason. This is the same thing that's now happened to me twice. The first time it happened Sonicare did replace the handle and I got another year of use, but now this one has also died. There's clearly something wrong with this product and the company has no other solution than a 30% off discount with free brush head for your money and time. DO NOT BUY!

[This review was collected as part of a promotion.] The iphone app is not good. - First, it always ask me to start on one side, while I want to start on the other side (think of left handed/Right handed people). - The app detects I am using the brush, but it does not know which segment I am in. - Instead of normal cleaning of 2 min, it usually goes for 4 min - 2 cycles. - It is normal for people to take their phone to do this kind of stuff. Initial use of the product - it is ok. But, after a week, it is useless to take the phone and use it. I just stopped using the app. It is not as intelligent as it claims. Also, the 6 beeps to change tooth segment.... Just does not seem to work for me. I prefer 3 beeps to change - Top Front, Bottom Front, Bottom Back, Bottom Front. This seems more logical & easier from a hands movement.
