[This review was collected as part of a promotion.] I received my OralB - iO Series 7G Electric Toothbrush, Black Onyx to test and review. I live this toothbrush along with the app it’s helping me keep better track of my tooth care. The app is super easy to use and makes it easy to make sure your brushing lie you should be.

I bought this product several months ago (about a year now) and at the beginning it was great. My teeth were clean my mouth felt healthy, until the black mold started showing up. Just an FYI after every cleaning remove the brush head and rinse it with water. Even after doing this help clean the gunk out, I still have some black residue that is on the brush head and tip of the brush unit. Wouldn’t recommend as my Sonicare was much easier to clean. I’ll be selling this one and getting a Sonicare for this reason more simple features.

The was a great purchase at first. While the brushing ability is very good. The app and the the ability to sense which section of teeth your brushing has gotten very bad. 5-10 seconds for it to sense that you have actually changed positions. Definitely not worth the money at this point. I have only had it 4 months

The brushes seem good but please notice that the 2-pack only comes with 1 additional replacement head. I thought there would be an additional replacement head for each but instead there are only 3 total heads in the package. So my wife has a replacement head and I do not. I should have paid closer attention to the description and not assumed each brush comes with a replacement head. I think this 2-pack would make a lot more sense with 4 total heads. Just strange to call this a bundle if it is designed to be shared with two people but only one gets the extra brush head.

[This review was collected as part of a promotion.] this is the best toothbrush I have ever used! I have ways used electric toothbrushes and thought they worked pretty well until I came across this one. I love that you can pick different brushing settings and that it tells You how long you have been brushing for.

[This review was collected as part of a promotion.] This Oral B io7 series electric toothbrush brush is the best thing I've ever used! It was very easy to set up and charging is very fast. I love how it has different colors around the neck of it to indicate if you're brushing wrong or right. I've been using "whitening" mode for brushing and I truly do see an immaculate difference! I can't see myself ever changing toothbrushes again, I highly recommend this to everyone!

[This review was collected as part of a promotion.] When I say I’m beyond impressed with this toothbrush let me tell you I really really am. This is a toothbrush you can set different color lights to has many cool features and bonus you can download an app for it. It has Bluetooth and charger how cool is that!

I got this for Christmas and it is by far the most advanced toothbrush I've ever owned! I feel like it gives me a great clean and I like that the app helps you improve by showing you where you should focus more time. The brush head is much thicker than my old sonicare toothbrush, so it takes a little getting used to. I'm also finding that I drool/drip toothpaste/saliva while I'm brushing due to little vents in the brush head. I'm not sure if I'm doing something "wrong" or if there is a way to avoid that, but that's why I knocked it down 1 star.

[This review was collected as part of a promotion.] Wow!! Can I just say if one could love a toothbrush like a favorite blanket, this would be it. The sittings for each brush is just amazing, we will be adding one for each grandchild. The teen lives the colors to choose from and the sitting to fit him and not just a toothbrush.

Lots more technology than my old Oral B type 3728 professional from 2017. I would rate the toothbrush itself 5 stars. I have an IO9. The Oral B app I would rate at 2 stars. I don't believe the Coverage information that I am given is accurate. 85 to 85% coverage is NOT accurate. I have tried the suggested tooth to tooth and then breaking my brushing into quadrants and I am ABSOLUTELY sure I am hitting ALL tooth surfaces. If you use the unguided portion then all you get is the brushing time and overpressure. The best session score I have had was the very first time that I used the toothbrush. It was a 76. Tooth Coverage was 97%- time was 2 min 53 seconds and over pressure was 4 seconds. The session scores are NOT encouraging when so much is deducted for a SLIGHT overpressure. I bet there is not a person on the planet that can brush their teeth and not have a slight overpressure somewhere. I think the App was meant to encourage good brushing techniques but I find it to be very discouraging when I do my best to improve using the coaching tips and sessions scores dip or never improve. I would like ORAL B to look at coming up with some way to better score the sessions. Again accuracy of brushing using the guided portion of the App just does not appear to be accurate.
