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). Select reviewers may receive discounted products, promotional considerations or entries into drawings for honest, helpful reviews.

    Pretty great and fun to use, I would say one down side is the AI with the phone doesn’t match sometimes, I’m brushing a specific area and the phone will say I’m brushing something else.

    Best toothbrush I've ever used. At any age, it's important to brush correctly. By using the phone app, you can see where you need extra brushing, you are scored every time you brush.

    It’s a great toothbrush you can’t go wrong with it. Probably, the only reason why I don’t like it as much is since, you if you touch the button below the power it you end up not only in a different brush but also, in another language. Lol.

    This toothbrush is one the Jetsons would use! Oral B app is what really makes it fun and interesting to use. Allows you to keep track of previous sessions, scores, enabling you to compete with yourself.

    Great Toothbrush! The 3D guide in the app is terrific, although some of the time the app thinks the Toothbrush is brushing the wrong area.

    Times change, and I have advanced with Braun. This one has all the bells and whistles. The brush heads on this one really take care of business. You just adjust the motor to your cleaning strength.

    I carry a great deal about my dental hygiene, and my dentist strongly recommended that I invest in an electric toothbrush. I just like getting achievements for brushing my teeth.

    BestBuy Curbside Delivery is Terrible

    The product is good but the Service of BestBuy was terrible. I gave it 2 stars so you can read what is written below We went for the curb side pick-up at Reston, VA location. A store person was called and he said he will bring the item outside, it was 5:42 pm and the store closes at 6:30 pm. Stood outside for 45 minutes, no one showed up or picked up our call and we finally had to leave just to return the next day and pick-up the item. I understand it's not easy to become AMAZON but i am sure one can learn a trick or two. Next time you are forcing us to buy from AMAZON as these are not BestBuy exclusive products.

    Great quality of electric toothbrush, but a lot of the features that are included aren't entirely necessary. Lots of other toothbrushes out there that are cheaper, and still get the job done.

    No, I would not recommend this to a friend
