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.

This summary was generated by AI based on customer reviews.

The vast majority of our reviews come from verified purchases. Reviews from customers may include My Best Buy members, employees, and Tech Insider Network members (as tagged).

    Needs a better design so toothpaste doesn't go down the handle and make a mess.

    Overall this is a decent toothbrush. I am on the 3rd week using the io9 and when I brush my front teeth the noise from the brush vibrates my head slightly. I never used the app for the tracking as I feel that is useless feature

    I have a very small jaw and i couldn't get to the back teeth. The bruch heads are very bulky for me. The set up was wrong from what the information on the inside said and then it listed items inside that were not there. The inside panthlet mentioned bruch head storage. Which there was none. Generic stuff that doesn't apply to my toothbrush. Very disappointed. They need an option for people who can't jam a bulky toothbrush in their mouth, maybe a smaller brushhead? Will be buying the Sonicare Phillips one.
