I bought the iO Series 7G Electric Toothbrush Black Onyx three weeks ago and I am very happy I did. I have used other electric toothbrushes from Oral-B but this iO series changed the way I brush my teeth. The teeth look clean and the gums are healthy. The bluetooth connectivity from the toothbrush to the Oral-B App on my iPhone provides realtime information where I am brushing and whether it is with the right pressure. The toothbrush has pressure sensors and a colar indicator of Green (right), Blue (under), or Red that is excessive.

I bought the iO9 8 months ago and the battery already stopped working. The toothbrush won’t hold a charge at all! I even was careful with it, only charging when it was completely drained and not over charging it. I was excited to use this product since it was my first fancy toothbrush. It’s so disappointing to have something so expensive to fail working in less than a year… Skip this model and buy a cheaper one that will last for years.

[This review was collected as part of a promotion.] This is a great toothbrush! I love the different settings for different types of cleaning. I've been using the whitening setting along with some whitening toothpaste, and I've really noticed a difference. I also like the timer function to stay on track.

[This review was collected as part of a promotion.] I absolutely love this toothbrush. Its rechargeable and light weight. I love that its not super loud. You can change the color on it which I think is so cool. I also love the fact that it starts vibrating once you've brushed your teeth long enough. I highly recommend this tooth brush if you like electric ones its simply amazing.

This is the best brush that I've ever had. I had a dentist appointment today. The hygienist commented on my teeth the whole time. She said that I have the cleanest teeth she's ever seen. She said that she was trying to find plaque and couldn't. I was her easiest "cleaning" job she's ever had. She asked what toothbrush I used and was very amazed.

[This review was collected as part of a promotion.] This is a great product. My husband loves that is is rechargeable and he does not have to replace batteries all the time to use it. It took a bit of time for him to understand how it works since he has sensitive teeth and he used the brutal mode. I told him there was a sensitive mode and he loves it

[This review was collected as part of a promotion.] I bought this toothbrush and was originally put off because of the price. Let me tell you it is very much worth the price. Everthing that this toothbrush does from tracking how long you brush to being a rechargeable one at that with replaceable heads. This toothbrush does it all and does a really good job of cleaning my teeth too.

[This review was collected as part of a promotion.] I got this product a while ago, and am very pleased with it. I love all the features, which include a timer, to show how long you brush and a happy face, when you brush long enough, and a sad face when you need to brush longer. It does an excellent job at cleaning teeth. It leaves your teeth with a dental clean feeling.

[This review was collected as part of a promotion.] I’ve been using this toothbrush for a few weeks now....not only do my teeth feel cleaner overall, but the technology of this thing is awesome. You can connect this toothbrush to your phone via Bluetooth and keep up with your cleanings on an app. My favorite part about this toothbrush is the colors it changes to while brushing my teeth.....red-brushing to hard, green-good brushing, blue-brushing is too soft. I tend to brush my teeth to hard, so this keeps me in check. Last, it has 8 different brush modes and keeps track of the time you brush- giving you a smile if you brush for 2+ minutes. If I could give this toothbrush more stars I would. It’s the best and coolest toothbrush I’ve ever owned!

[This review was collected as part of a promotion.] I received this awesome electric toothbrush. I have always wanted one and now I get to try it out. It works great and I can feel the difference between the electric toothbrush and a manual toothbrush. The electric toothbrush makes my teeth feel cleaner.
