Customers are saying

Customers recognize the iO Series 9 Connected Rechargeable Electric Toothbrush for its exceptional cleaning capabilities, overall performance, and ease of use. Many appreciate the long battery life, useful app, convenient travel case, and helpful pressure sensor. However, some customers find the price to be high, and others have noted that the brush heads are different from the older Oral-B design.

    I'm not sure if all the functions on this 9 is worth the money or not. If you brush your teeth twice and day you're not even thinking of using of different functions or even get your phone out to monitor your progress every time you're trying to just brush your teeth. Lower series can probably clean your teeth just as well. Other than that, I love it.

    I really Enjoy using this toothbrush. I love all the features especially the teeth mapping function which shows what areas you may have missed or need to spend more time on. I definitely focus more on cleaning my teeth and definitely spend at least two minutes or more using this toothbrush and the app.
