Provides very thorough cleaning. My only concern is lack of accessories. The less expensive model, the iO-7 comes with brush head holders, how come the top of the line model, the iO-9 does not?

I have been enjoying my iO Series 9 toothbrush for 2 years I have not had any problems Dental check ups are always good and I noticed the Dental assistants have an easier time cleaning my teeth I also enjoy zero pain

I've just started using my Oi toothbrush but for the price paid, I can't believe it doesn't have a little plastic cap to go over the brush head when on the charger.

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.

This was my first time trying an electric toothbrush and I wanted to make sure I purchased the right one so I went with Oral B and just WOW! I love it, I'm never going back to a regular toothbrush again!!

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.

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.

The ultimate tool, a must have for each tooth you have ! Do not wait , if you do you will slap yourself when you finally do decide to buy the best oral cleaning tool ever!

I get great results using this toothbrush as directed. I am pretty upset that for the amount of money I put out, there is no travel charger. I guess its back to manual brushing for my next long trip.

I have never felt my teeth so clean even after a cleaning at the dentist. This this is worth every penny. How did I ever live without it. Convincing everyone I know to get one!!
