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.

    Cleans well. But coming from the Premium series im very very disappointed with battery life. It lasts only one week and if i turn bluetooth off it lasts 8 days. Also that stupid screen that you cant even see while brushing your teeth turns on with the minimal movement. Transporting the toothbrush expect to lose some battery live just for the normal movement of a bag.

    Comparing it to Sonicare…no wonder dentists recommend it to be #1. Great product. Cleans through each tooth.

    Amazing electric toothbrush. several different setting that should have a setting for everyone. Personally my gums are sensitive so had to put it on the lowest setting until I got use to then adjusted up to the higher settings the more I used it. Toothbrush will ask you if you have replaced the head of the. toothbrush. Toothbrush also has different colors to let you know if you are applying enough/just right/to little pressure.
