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.

    It’s a good toothbrush but it doesn’t feel like it’s getting every angle of my teeth and basically sprays toothpaste everywhere. The in app guide is only half responsive and doesn’t tell you that you’ve got a good clean in that part of your mouth for a while after you’ve started, you may spend 3 minutes on that part of your mouth until it registers as clean.
