I have this since 2 weeks ago and it has made a real impact in my life. I no longer need to put so much pressure on my gums, thinking that I am not cleaning enough... The brush does everything and the app couches you!

Took a while to get use to the IO cleaning system as I have used Oral B regular spin brushes (Triumph) for years. The I0 handle is much smaller and easier to use and seems to clean better than the Oral B Triumph system.

Product is fine but the charger is not smart. If you keep the device on the charger, which is super convenient, it will prematurely kill your battery. My toothbrush lasts no more than 5 seconds a month after the warranty expired.

I have been using the iO for a week instead of Sonicare Diamond Clean: the iO has a more refined display, better Bluetooth connectivity, and better cleanings

I like the toothbrush but this is my 3rd one. They seem to stop working about 5 months in. Not sure what I'm doing wrong. 🤔 I just ordered another one.

I bought this to replace a competitor's model, and it seems to do a much better job of cleaning teeth and removing plaque. On the downside the app gets confused as to where I am brushing. I see no evidence it monitors 16 zones. More like 6.

I bought an iOS 7 toothbrush about 7 months ago. It has already stopped working. Poor quality?? I’m not sure, but I do know that I spent a lot of money for something that did not last.

Motion sensor on toothbrush will continuously drain the battery when the toothbrush moves around in case or bag. Any slight movement will turn on display. Must charge DAILY which is very inconvenient for traveler.

This toothbrush truly made my teeth feel like I just left the dentist office. It is a way different experience and gives a different feel from other toothbrushes I have used.

The brush looks and feels great. However, no matter all the different troubleshooting methods I try, the brush will not connect to the app. Very disappointed.
