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 differences in the iO brush heads compared to older Oral-B designs.

    Packed with features, great battery life, and reliably reminds you to change the brush heads. The mobile app is a great extension to this toothbrush. Allowing for even more in depth control and features.

    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.

    Very well manufactured, you can tell a lot of thought has been put into the end-user experience. If you're looking for the best toothbrush money can buy, this is the one. Especially excellent traveling case with a built-in charger. Tooth detection of which area in the mouth you're brushing is accurate about 70% of the time, but can be annoying when it's wrong.

    To be completely honest. The first week of using this thing it is absolutely amazing. After about two or three months, you question if it was worth it. It doesn't seem as powerful anymore, and I wish the app was better. I don't think the extra modes really do anything differently. I think it should be cheaper. You can't pause it if you need to add more toothpaste which is super annoying. The lights are really confusing too after awhile you'll realize it.

    Very impressive. The technology behind this toothbrush is very good. I have used several different brands of electronic toothbrushes and this is by far my favorite. Has several different settings depending on the level of clean you want. App is easy to use. Gives you that straight from the Dentist clean.

    This is an awesome toothbrush and app. I was using Quip before but this one is far superior. After the very first use my teeth felt much cleaner. Awesome quality!! Best Buy had the same price as all other retailers and I trust them, that's why I ordered from them and they (as always) came through with packaging, shipping and delivery.

    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.

    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.

    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.
