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 product is the Iphone for toothbrushes. The toothbrush is really easy to set up. This is the first time I seen a display screen on a toothbrush. I highly recommend you use the “super sensitive” mode for less pressure on your gums and teeth.

    Does a good job cleaning your teeth. The app is hit or miss as far as areas of your mouth that have been cleaned. Some of the different brush settings seems a little gimmicky but all in all a good toothbrush if you have the coin to spring for one

    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.

    It is a very good product with only one drow back - the are no 2 min stopping. You have to have a perfect hearing to hear 3 bibs that specifies 2 min cleaning time. For older person it may be problematic.
