[This review was collected as part of a promotion.] As someone who likes data and numbers, a toothbrush that provides a look at the quality of my brushing in an app is a dream come true. The 5 brush modes are great as I know that I have more sensitive gums than most, and really appreciate a smart toothbrush that is supposed to address that. I usually use just a standard toothbrush and brush for about a minute, so it is a little different to brush for two, and to have the toothbrush itself signal when to switch. I have a few problem spots so I'm hoping this will help me ensure I get those areas every time! I'd recommend this to anyone who needs to up their brushing game and especially those interested in diving into the app.

I bought this about 2 months ago and was excited to have the capability of detecting when I push too hard on the toothbrush. I found out that I am not a major offender and it happens less than 2% of the time. Pros: The unit indicates when I push to hard with I am brushing. Cons: the brush body gets very slippery when the saliva migrates down the brush to the body of the brush. Sometime I can barely hold onto the brush. The brush heads are only effective for about a month for me. After 3 weeks I begin to notice that my teeth don't feel as clean as the day goes on. After 4 to 5 weeks, I can notice the difference right after brushing. I change the brush head and everything returns to Clean and Fresh. I bought a two pack of the brushes, so I could leave one of the brushes in my travel kit. The toothbrush in my kit lost the full charge in less than 6 weeks and I was very surprised when I tried to turn on the brush while visiting my sons house. When I brush without using the App, the saliva and toothpaste mixture keeps onto the brush while I brush. It gets to the point where I obscures the display that tells me when I have completed the 2 minutes. It would be nice if the brush generated a different tone, or pause when I hit the 2 minute threshold. The app is a good idea, but I have to stand straight up while brushing in order for the sensors to detect the area that I am brushing. When I stand straight up I tend to express more saliva/toothpaste mixture onto the brush.

They look better than they have in a very long time. It has a pulsation built in. It comes with a magnetic charging stand. It gas several cleaning modes. I am thoroughly impressed with this tooth brush.

[This review was collected as part of a promotion.] It came in a neatly packed box . The oral b io series is the best, I could ask for. It’s so gentle on teeth , it has a very good micro vibration.The round brush, helps I professional cleaning.There is a smart sensor, that protects your gums and enamel when u brush too hard. So you can see the sensor react and brush accordingly.They have this new feature that is called 3D tracking and AI recognition it uses an interactive color display. This helps us to clean all areas of the mouth, it guides us where to clean and how much pressure is needed. There is a 2 minute timer, which warns us every 30 second.The brush comes with 7 modes like daily routine,gum care,tongue cleaning,whitening,sensitive, intense, super sensitive. You can sync it to your smart phone. So your smart phone can remind you on updates, there is a happy and sad smiley.. the sad smiley means u either skipped brushing or did not brush effectively. The happy smiley, says ur tooth is healthy. This helps in tracking your brushing habits. I got -3 replacement brush, travel case, charging unit. My tooth are really sensitive and I spend a lot on dentists and hygienist.. This has been the best, by far , I can vouch on this brush. In this 3 weeks , I can feel how good my tooth has changed. It’s stronger and healthier. It helps me clean the places that I missed. It guides me, where to brush. Definitely, would recommend to my near and dear.

[This review was collected as part of a promotion.] This is the most nicest and fanciest toothbrush I’ve ever seen! I love everything about it! I downloaded the app and tried to connect it to Bluetooth but have yet to be able to connect my brush to the app. I don’t know if that’s necessarily an issue with the brush or maybe the Bluetooth on my phone. The app will say it’s searching but it never connects.

[This review was collected as part of a promotion.] I received the Oral-B iO9 Series toothbrush to try out and it works well above what I expected I had an electric toothbrush before I received this but I can easily tell the up in quality. I can actually feel the difference! My teeth feel a lot cleaner than usual and I feel I don’t have to brush my teeth extra times to keep my teeth feeling clean. All of the additional perks like the digital display, the different setting (I use daily clean), etc. I LOVE IT!

[This review was collected as part of a promotion.] I’ve been using this toothbrush for a few days now and so far it has been great! The vibration is very powerful but the bristles on the brush head are nice and soft so it is a great balance. The many different setting options are nice and convenient, you pick a mode depending on what type of brush you’d like to achieve, such as daily clean or whitening mode. I like that the light on the handle helps guide you to using proper pressure. The toothbrush itself is very sleek and nice looking along with the magnetic charger. There is also a Bluetooth connection, to use with the app. I did have some trouble connecting to it but it offers some great additional features including which zones you need to focus more on and reminders when you need to change your brush head. There are just so many endless features, it’s a really neat toothbrush!

[This review was collected as part of a promotion.] I got this as a gift for my father for father's day and HE LOVES IT. He is a big fan of electronic toothbrushes and he has said that this is the best one yet. The magnetic charging is so easy,; also the numerous settings are so handy. I would recommend this!

Design flaw. There is a hole in the neck of the brush head, over time mold builds up and it's impossible to take apart and clean. Nothing fits in there to clean. All their suggestions of rinsing, wiping and air drying don't work. Build up/mold not covered by warranty. It's a health hazard. Do not recommend.
