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.

    Really wanted to love this toothbrush especially with the cost. After using it for about a year and a half, it started to act wonky. I would fully charge it, and after one use it would either turn off on its own, or display that there's no charge. I rinse it off with water and dry it every time it's used. I returned it and got another one (protection plan), and the same issue is occurring after a year and a half of use. I don't use half of the features on the app, so I might just downgrade to a cheaper oral b io toothbrush. i love the rotating brush which is why i want to stick to oral b.

    After 2 weeks that I bought this toothbrush just stopped charging, I tried in different sockets, I reset the device and nothing happened. The toothbrush cleaned really well my teeth but the battery dies really quick. I followed all the instructions, I fully charged the device the first time. I'm glad I still on the period time to return it to the store because it is very expensive for a toothbrush. Don't waste your money

    Combines the sonicare stroke speed with OralB rotating brush. I've had both in the past, this blows both away.

    It’s okay. It has two small slits in the toothbrush head that drip while you’re brushing your teeth.
