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).

    Excellent toothbrush. There’s a lot of modes to use to make sure that your teeth, gums and tongue are cleaned well. Very soft bristles.

    As an avid Sonicare user, I thought I’d give this a try. My only regret: not doing it sooner. My teeth have never felt cleaner.

    Ideal for people who are learning to control the pressure on their gums and teeth with the sensors and the "ultra semsible mode" you will love it.

    Great device. Have not felt my teeth cleaner with the traditional tooth brush. Highly recommend especially for those who tend to have build up between dental cleaning. App a bit buggy but confident it will improve.

    Oral B IO Series 9 is an excellent electric toothbrush. It gets my teeth really clean. Note: The toothbrush is on the expensive side. If you do not want to pay $250 -$300 price range then get the IO Series 7 or 8. It's the same toothbrush as series 9 minus gadgets (i.e. color screen, 3D app that maps your teeth as you brush and chargeable carrying case). I am just a gadget guy. ☺
