I have another Oral B I0 series. I needed to get a second one for a different brush head. Now I do not need to change heads each morning and night. It is not as loud as my first one. I like the design of the head as well. I recently made the switch to electric from "manual" and wish I had done it sooner! My periodontist recommended it.

I’ve had an older model for years and de died to upgrade. I like the size of the brush heads better with the traditional oral b spins.

Title says it all. Who needs Bluetooth and 20 brushing modes. This thing brushes and has an on/off button and charges and lasts.

After a suggestion to give the Oral-B iO series a try, I am pleasantly pleased. Easy use and set up. After use, my teeth feel really clean. I'm still learning how to maintain the right pressure which the indicator lights show during brushing. Overall, glad I purchased it.

Some regrets on this purchase... I did a lot of research on the Oral-B toothbrushes and this model is probably a little better than the cheapest model. First disappointment is that the description includes a Travel Case but this product sold by Best Buy does not have a travel case so beware when doing a price comparison. I probably should have returned it to Best Buy. It as 3 cleaning cycles but doesn't display the cycle like the higher end models do. The handle vibrates for the cycle and it's up to you to figure out what that means.
