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).

    Oral B -iO Series 9 Brushing Made Better

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Quality of Oral B -iO Series 9 is exceptional. I will say the software that monitors how long you brush and if you get every area isn't always accurate. That would be my only complaint. Assuming it is a software bug but even so it is making me brush longer then I used too and be more aware how well I am brushing. I also like the various settings on the unit. I would highly recommend this product.

    An ellecent tooth brush in combination with its app, really shows the areas you miss and maybe dont think to brush enough. You can even charge the toothbrush theough the case which makes my travleing aspect of my job that much easier.
