    This toothbrush has solved my OCD in my mouth!! It is a little expensive for a toothbrush but well worth it when you have fresh clean teeth all day!

    The app feature is nice however I do not open my phone to view. The brush does "beep" when prompting to move onto next brush area.

    Although this is an expensive toothbrush, I’ve used sonicare for years and never had any cavities. Love the Bluetooth feature on your phone!

    Best toothbrush on the market, although I have not made the app work successfully and my old one went dead after about 4 years of my wife and I using. Still got another one.

    This toothbrush has done amazing in such a short time. My gum health has improved and my teeth have gotten whiter. Defiantly worth the money.

    Does a great job brushing - none better. Replacement heads are expensive, as are other brands also.

    This brush does an exceptional job of giving you the feeling you just left the dentist. However, the app isn’t that great. Has a hard time identifying where I am brushing. Probably not worth the $200 price tag though.

    Works great but is entirely built around you having the app open. You can still brush without the app and it will go through each phase but it won’t give acknowledgement that you did brush
