[This review was collected as part of a promotion.] When I got this I was worried about hoe hard it would be to work it with the Bluetooth option it gives. And honestly it was a little confusing and I'm so working on understanding it. But I love the fact that it can tell what size you are brushing and how well you are doing it. I love that it tells me if I am applying to much pressure or not enuf pressure. And I love that I can choose what option I want to use when brushing like whitening ( I love this setting) or sensitive and daily clean along with a few others. It also reminds me at the end of brushing to swish with mouthwash and to brush my tongue. I love that it is rechargeable and I can just set my brush on the charger. Also the fact that it comes with the most amazing case ever and it has a magnet that closes it so nothing can get in it.

[This review was collected as part of a promotion.] I got the iO7 Series Black Onyx and have been using it for about a week now...I love it. My teeth feel so much cleaner. It is very easy to use and set up, its light to hold so you can really control how you use it. The rechargeable stand is very slim so it does not clutter your sink. I have it attached to my Bluetooth so i know how long to properly brush my teeth. The brush is gentle on your teeth and gums. I am very happy with the iO7, it is a family must have.

I like this toothbrush very much. However, I have a couple of problems. The toothbrush comes with 2 brush heads, but you can't tell one from the other. I had to paint a mark on one of them for my wife. What happened to the little colored plastic rings? Further, there is no brush head holder. I would really like to stand them up in a holder by the sink, but that did not come with the Oral b iO9 toothbrush, and it APPEARS to be unavailable anywhere. Why is that?

We've had this toothbrush for 3 months now and I LOVE it! I use the app, hubs does not. I was an occasional flosser, but now I floss every single day :) It's ridiculously expensive, but I love techy things and honestly I have zero buyer remorse. I think this toothbrush is worth every penny and I really like the travel case/charger.

I usually do write reviews, but this brush deserves a good review. This toothbrush has such a smooth feeling to it, truly is one of a kind. Favorite part has to be the timer since I don’t always brush enough without setting a timer on my phone, luckily now this can do it itself.

[This review was collected as part of a promotion.] Oral B always makes great toothbrushes! Love the features on this. So many choices for how I want to clean my teeth. I love the power brush because I don't have to wonder if I'm scrubbing hard enough or not, the brush does it for me!

[This review was collected as part of a promotion.] I love lovs love this toothbrush!!!! It cleans so well and gets in between all the cracks and crevices that regular toothbrushes can't get too. The blurletooth feature on this toothbrush won't work. I can't connect to the app. I downloaded the app like instructions said too and opened app but it just keeps searching for my toothbrush.

[This review was collected as part of a promotion.] Right up front the basic brushing is great, but this is supposed to be a premium device that goes beyond basic brushing and this is where it misses. First off, the brush has no memory to upload your brushing coverage after the fact. Who wants to have to always use your phone and brush to gain those insights. Maybe my phone is charging elsewhere... maybe I'm using my brush in the shower. So the feature wasn't really thought through for the price point and really offers very little benefit given the limitations. Additionally, the travel case should support USB charging to eliminate the need to carry a separate charger. These may seem like small details, but that is what should distinguish a premium device from the entry level.

Design flaw. There is a hole in the neck of the brush head, over time mold builds up and it's impossible to take apart and clean. Nothing fits in there to clean. All their suggestions of rinsing, wiping and air drying don't work. Build up/mold not covered by warranty. It's a health hazard. Do not recommend.

The app is nowhere near accurate. I start in lower left third, and the app shows I'm starting in lower right, or sometimes in the upper right third. Because of this, an area will show as being completely finished, when I haven't even brushed on one of the surfaces (inside, outside, or top). Also, sometimes the toothbrush doesn't mark the 30 second intervals, so I don't know how long I've brushed. This is the second iO 7 I have owned, because I returned the first because I thought it was malfunctioning for these reasons. I talked with customer service before returning, and their response was to replace it. Obviously, the problem is not with the toothbrush, but with the app. Fix it.
