[This review was collected as part of a promotion.] I started using this item about a week ago. I have already noticed a big change in my teeth. Works great at removing plaque & making my teeth feel great. Using this has made my morning routine a whole lot easier

[This review was collected as part of a promotion.] I've loved how clean my teeth feel after using this electric toothbrush. I enjoy the different settings/brush features, and the fact that the toothbrush times my cleaning. I feel like I will be very satisfied with the quality for a long time, and look forward to having a clean and fresh smile! :) I'd definitely recommend this brush to others!

The high price is ongoing - io heads are considerably more expensive than others- but should be justified by the app. Unfortunately the app regularly misdetects which portion of the mouth the brush is on, resulting in unreliable guidance on cleaning. Hopefully this will be resolved in a future update.

[This review was collected as part of a promotion.] I recieved this and love the fact that I can switch between a whitening setting a sensitive setting and a deep clean setting but even on the sensitive setting it hurt my teeth and gums so bad maybe it just takes some time to get used to

[This review was collected as part of a promotion.] It had been almost a decade since I got my first electric toothbrush. The new ones are much different. The oral b has a much easier charging station,is very quiet, has a sensor for correct pressure , not to mention a timer for correct brushing times. Overall a great product that I wish I’d updated years ago.

I purchased 2 of the IO9 toothbrushes from my dental office within the past month. The staff was ranting and raving about how wonderful these toothbrushes are and how many features they have. I was super excited until I realized that the toothbrushes that were purchased from the dentist's office lacked several features that I was told about by the staff. This is very upsetting especially because of the price. The toothbrush works well however lacks several of the features.

The Bluetooth is abysmal. Half the time it doesn’t understand that I’m in a different quadrant. I could easily get over that but wanted to mention in case you’re a completionist like me and wanted your health app to keep track. Most importantly is the mold. I’ve had this brush about a month and I brush twice a day. I take the head off after each brush and since the bristles and inside the head and base. One day I noticed some blank gunk. I thought maybe it was the design. After careful inspection, I realized it was mold. I’m going back to sonicare flex. That toothbrush lasted over 7 years and I wish I hadn’t thrown it away for this moldy garbage. I’d never recommend Oral B I/O.

[This review was collected as part of a promotion.] This toothbrush is awesome! Not only is it full of technology, but it also cleans my beautifully! You can customize the color ring, decide if you want a normal, densities, whitening, intense or gum brush. The app is so cool and handy as it can guide you to keep a good pressure and also spend the perfect amount of time on each section of teeth. The brush holds charge really well and is SUPER powerful. My teeth feel so good after brushing now and I’m constantly rubbing my tongue on them!

[This review was collected as part of a promotion.] To be honest I never knew I needed a smart toothbrush until I had the eCOMM in hand and in my mouth. This thing is amazing!! It's nice to look at on the counter and it does it's job on my teeth. If you have the money to spend on a toothbrush, this is definitely the one to spend it on

[This review was collected as part of a promotion.] This product comes with extra brushes. It’s very sturdy. Feels super nice . Let’s you feel refreshing after doing absolutely nothing but holding it. Small tip to get them pearly whites clean . I would recommend this to anyone that hates brushing
