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.

    Better than Sonicare in my opinion, more powerful and the app works better. Can’t speak for long term use but I had two sonicare diamonds in three years, and both failed. One because of the battery and the other the motor just stopped working. So far good experience with this and feels like a dentist cleaning.

    Was a present for my mother who kept saying she wanted this toothbrush and she loves it. She says she doesn't know all the features but takes it every where she goes.

    Switched from Sonicare to this Oral-B and couldn't be happier. I like the little screen and timer that let's me know when I'm done and shows the time and i also like that it shows red if I'm pushing too hard.

    This is the best brush I've owned and it makes brushing fun again. That app is pretty cool and the brush head attaches easily. The device is easy to clean with very little nooks for toothpaste to hide. The charger is small and easy to store without taking up much space. The travel charger case is really sleek and convenient.

    Why did I wait so long to switch to Oral B?

    My dentist told me I was brushing too hard. He told me about electric toothbrushes that would signal when I pressed too hard. I made the switch from my old Sonicare to this new Oral B - iO. I thought it was nuts to spend almost $300 for a toothbrush. Nope! Worth every penny. I’ve never used a round head toothbrush but I feel my teeth are cleaner after brushing. Easier to brush my back teeth. Also, love the colors that indicate red for too hard, green for just right and white for too little pressure. Easy to clean the brush head and the handle. Great purchase!

    Wow! This is the best electric toothbrush I have tried. I had plenty of doubts at the beginning to purchase it but I decided it to try it. My teeth have never felt cleaner and whiter. It is just amazing all the functions that it has. It’s like having a coach to tell you how to brush your teeth properly.

    Best Brush I have ever owned. I didn't think I would like a round brush or I didn't think that there was enough movement in the head spinning to do a good job. I was wrong. This is a great brush and cleans way better than the conventional brush style brushes.

    Very well thought out program. While I do not get too in to the blue tooth capability I find that the toothbrush does what it is supposed to do--clean my teeth really well. I upgraded from the Oral-b 8000 which in of itself was a highly rated brush. This one with its new brush heads is the best

    This electric toothbrush is by far the best in the market. I have tried many battery operated toothbrushes in the past and this one definitely blows every single one of them out the water! Definitely recommend giving it a try.

    Luxury looking electronic toothbrush! I love all of the features including daily clean which I use with the Bluetooth feature. It shows how long and where to brush your teeth. It even shows where and how long you’ve used too much pressure. I highly recommend this investment!!!
