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.

    That’s a new generation of tooth brushes. I had whatever was invented, but this time it’s really impressed. The app works great, you can control the progress of your brushing, I love it! Strongly recommend!

    What I love the most about this electric toothbrush is how it works with an app that will show you, as you brush, if you are getting all areas of your teeth clean.

    Great toothbrush. The vibrations take a bit of getting used to but once you do, its awesome. However, I did return this to buy a two-pack for cheaper the price and a big box store.

    I love this brush, but its my second one in less than 5 years. The battery just stops charging or as with my most recent, after a little over a year, it instantly drains from 100% charged to zero in literal seconds. Cant get one section brushed before it dies again.

    Great toothbrush. The app helps learn how long and what pressure to get all your teeth clean. Replacement heads are very expensive.

    Quick charging, good app integration, tracking is a bit touchy but if you go slow (as you should anyway) it works well.
