[This review was collected as part of a promotion.] I do like this toothbrush. I had a really rough time getting it to sink with my Android phone, but finally got there. Frankly I do not use the app really after trying it out. I LOVE the toothbrush though. I use the gum health setting usually, but once a week or so I use the whitening setting for my front teeth at least. My teeth feel and look amazing. The timer is great and really does get me to brush my teeth longer. It's not like the toothbrush will tattle if I don't, but I feel guilty if a get a frowny face. The wireless charger is amazing too and takes up very little space on the counter. I would sincerely recommend the toothbrush, the app, not so much.

[This review was collected as part of a promotion.] Many years ago I had a fancy electronic toothbrush; I hated it. It just didn't leave my mouth feeling as clean as a regular brush. Since trying the Oral B iO7 brush, my views on electronic brushes have changed. I am IN LOVE! My mouth is cleaner, my teeth are whiter, and my gums feel healthier. This is not your average electronic toothbrush. It has multiple settings to choose from (whitening clean, sensitive clean, intense clean to name a few). It has a pressure sensing feature that will change colors to ensure you are applying just the right amount of pressure when brushing. Every 30 seconds the brush will vibrate to let you know it's time to move to the next section of your mouth and it's bluetooth capable for in depth tracking and reminders.

I am the owner of the Oral IO series 9 toothbrush who is having a lot of issues with the app used by the product. First off, the connection between the app and the toothbrush has not been dependable. I have always been able to restore the connection, but records/opportunities in-between are missed, and it is frustrating to continually deal with this issue. The bigger issue, though, is accuracy. Lately, the app has been reluctant to record any brushing in the lower left area and today it wouldn’t register any brushing in this area at all. I watched the app carefully while I brushed this area without ever seeing a change from the color blue, even with changes in pressure and positioning. After more than three minutes of brushing I finally gave up and, of course, the app told me that I had missed an entire section of my mouth which was not the case. The toothbrush/app combination is a wonderful tracking and educational tool when it works, but without a dependable, accurate platform for the toothbrush, this type of high-end investment is not worth the price.

[This review was collected as part of a promotion.] The iO9 Series Black Onyx tooth brush works great! It has different settings depending on what you want- daily cleaning to teeth whitening. The colored ring lets you know when you’re teeth are clean and you can move on to the next area.

[This review was collected as part of a promotion.] Love the toothbrush a lot but the characteristics that make the toothbrush so expensive and unique aren’t working. For example, the brush offers great opportunities through Bluetooth and connection to the oral b mobile app. Due to the lack of connectivity, I have to give the 3/5 rating. I may have received a defect toothbrush.

I have never been so excited about a product, especially a toothbrush, as I am with the new Oral-B I09. The technology is wonderfully matched with an app that gives you real time learning and teaching tips to be a better brusher. I absolutely love this product, it’s a must have for everyone.

[This review was collected as part of a promotion.] I really like the features on this toothbrush. It makes it easy to select what setting I want to help clean my teeth. The brush itself is very soft and gentle as it cleans my teeth. It also has a timer so I know how long I have brushed my teeth. The stand does not take up much room on the bathroom counter.

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.

[This review was collected as part of a promotion.] I love my new Oral-B IO9 toothbrush! I have found everything I need in one toothbrush! After so many years of brushing my teeth I can finally say that this toothbrush is the one that does an amazing job like it should be. This rechargeable toothbrush comes with a home and travel case charger and 4 toothbrush refill heads which gives a great start. I love that it has 7 smart modes that are very useful when coming to brushing you will definitely love the features. It also has smart pressure sensor so you will actually know how to brush your teeth and get the most out of it. What also blew my mind away was that I can actually download an app that it will show me 3D teeth tracking to ensure I clean each surface promptly and make sure I those hard to reach areas and make sure I clean them right! I also loved the colored led display that actually tells time and battery life and will show all features mention above. I can say I have everything I look for in a toothbrush in the palm of my hands and definitely recommend it to anyone! It is a life changer and I can't wait for when I do my dentist visit and see if I have been doing teeth cleaning promptly.
