Overall, the brush is great and the modes are fun. The feel is good, and heads work well and feel like they are cleaning. Now, the BIGGEST con / negative aspect I have with the product is that the brush heads have 3 "air flow" holes in them (don't know the proper term) that while you're brushing, water and toothpaste can leak through. While leaking it travels down the whole toothbrush to where my hand holds it, so after every brushing session I have to end up rinsing the entire toothbrush and my hand. This is -really- annoying unfortunately and after almost every brush session I ponder returning the product. It works great, feels great, and cleans great, but the feeling of saliva and toothpaste running through the brush head holes, down the toothbrush and onto my hand, is really annoying...

[This review was collected as part of a promotion.] Arrived in great condition, ive gone through a few electric toothbrushes and this ones the best one ive had. My teeth have never felt so clean! it really gets inbetween the gums, will not. be going back to a regular toothbrush thats forsure!

[This review was collected as part of a promotion.] I really like this product. I’ve never seen this before on shelves but this one is pretty cool! I love it! I was super excited to try it. I would definitely recommend this to anyone looking for a new toothbrush.

[This review was collected as part of a promotion.] So I have a always used traditional toothbrushes. I have always felt like that did not clean my teeth like they should. My teeth are so close together that I even struggle with flossing properly. With this toothbrush it actually clans my teeth and gets the bits the tooth brush always missed. The catching stand works great. The different speeds are great from transitioning from teeth to tongue to gums. I would recommend this to any and everyone

[This review was collected as part of a promotion.] This rechargeable toothbrush is simply AMAZING! It actually remembers your brushing habit.My teeth and mouth have never felt so clean and fresh. It also the pressure you use while brushing.ibwould definitely recommend. Great addition to a daily routine

[This review was collected as part of a promotion.] I have the i07 Series Black Onyx toothbrush. After using it, I will never go back to a regular manual toothbrush. It has pressure sensors which is wonderful because I have a tooth sensitivity. You can download the Oral-B app and it connects with bluetooth. It's easy to set up. You will not regret getting this toothbrush.

[This review was collected as part of a promotion.] This has been by far the absolute best tooth brush i have ever owned or used. After each brushing it has given me the "just left the dentist" feeling. The timer feature is great, even if i don't always hit the magic time goal. The LED lights to show appropriate pressure or brushing firmness comes in very handy. Having the a speed adjustment is just a bonus. The only negative is that i have been unable to connect by Bluetooth.

I bought this about a month ago and find it absolutely useless. I bought it because I got braces and wanted to keep my teeth clean. The app is annoying and the settings won’t stay set. I wanted to use the super sensitive setting due to my mouth being sore from braces but when I’d try to find the setting I’d find it locked on the app and I’d have to perform factory reset on it. Tried to return the toothbrush only to be told I couldn’t due to no longer having the original box. I still had the user manual and inside packaging just not the outer box and still was refused a refund. I will never buy anything with oral b on it which has always been my brand of choice for toothbrushes. Oh well, I’m sure my meager contribution will not hurt them any.

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.] This works great as an electric toothbrush. It gets my teeth clean in a way that a regular brush just doesn't. You can feel the difference. When I first started using it, my gums started to bleed (I read this is normal for when starting to use any electric toothbrush). I changed the brush to Sensitive Gums mode and it really helped me ease into it. The pressure sensor is fantastic. When you make too little contact with your teeth, a light on the toothbrush is blue. When you have too much pressure, the light is red. Just right and it glows green. It works every time and really helps get the most out of the brush. The design is also really slick. The all black looks great on my countertop. The one downside is that I could never get the bluetooth to connect to the app on my iPhone 11 Pro. I tried multiple times with uninstalling the app and reinstalling, turning bluetooth on and off, resetting the toothbrush. I tried it all. Unfortunately, there isn't great documentation or videos on this. Here's the upside though - I just admitted defeat and decided not to use those features. And the toothbrush is still really really great even if it can't connect.
