I love this toothbrush. It feels like a massage on your teeth! I feel spoiled every time I use it. The charge lasts for about a week which is great. I love this toothbrush so much I bought them for all of my adult children and their spouses for Christmas!

I love this product. It cleans my teeth well and delivers all its promises.

The vibration seems to really clean my teeth. I was disappointed that this uses different brush heads though since I had a small stockpile for my previous brush.

So $300 is a lot to spend for a couple of toothbrushes, but our old Oral-B's needed an update. I was hesitant to spend this much, but oh man this toothbrush does such an amazing job. Great screen with options and a clean that rivals my dentist.

The head of the brushes are huge. The mode is too strong even I used gum care, this brush still made my gum line up. It definitely damaged my gum line. Will return. Do not recommend it

After experiencing issues using the app with the Genius X brush, I decided to try the IO Series 5. It's worse in every way. The app is still awful. I can be brushing my lower left molars and it will think I'm brushing my top right molars. It's ridiculous how inaccurate it is. So I deleted the app to focus just on the brush. That's bad, too. The pressure sensor is wildly inaccurate and highly sensitive. It will say I'm brushing too light so I will slightly increase pressure and then it's red. Like… what?! And because it has some sort of movement sensor, it's constantly waking up when I don't want it to. As such, the battery life is atrocious. I will be returning it. I do intend to buy another Oral B brush but only if I can find one that doesn't have a movement sensor and has better battery life. I don't see those details on this site, so maybe I won't be buying one.

We purchased the black and white set, after 1 year of proper use and maintenance the black handled toothbrush began to mold at the rubber piece that is between the head and handle. After cleaning the mold off, it would return after a few days. Tgis is a health concern at this point. Oral B customer service isn't wanting to replace even under 2 year warranty. The toothbrush itself does seem to do a good job but not at the expense of mold growth.

The toothbrush itself is great. I can't say the same for the 2 toothbrush heads that were included. According to the instructions and with all toothbrush heads, they should be replaced every 3 months but these heads didn't even last 2 weeks before showing the indication that they need to be replaced. I'm hoping its just the samples and not the case with all replacements.

This toothbrush has a design flaw in the head that allows spit and toothpaste to leak all down the brush and all over you. The back of the head has multiple holes to allow mold from building up in the head but it makes a big mess every time you brush your teeth. The toothbrush itself cleans the teeth well but not worth the mess in my opinion. I returned.

These teeth brushes brushed my tooth so good, that it took 2 years of gunk right smack off. I could not believe it!! I was like Lordy B!!! My wife used it on her tooth and it took the color from dark green to a mild brown in under two weeks time!! Highly recommended for all. We was a thinking about getting after the hound with it to see just how good it is. I will report back later with full details!! Wow mine and the old ladies tooth feel so purdy, it’s only gonna get better. I can’t imagine having a white tooth!! Wow!!!
