[This review was collected as part of a promotion.] I was excited to receive this product because I am always looking for a good electric toothbrush. I was really impressed by this product because it cleans your teeth very well. Feels like you just came back from the dentist.

[This review was collected as part of a promotion.] iO9 Series Black Onyx electronic toothbrush is the most unique and helpful toothbrush I've ever owned and used. The design of the toothbrush is modern, sleek, digital with images and even shows hello message and a happy face! The best part is that it cleans my teeth so well - I am blown away by the results everytime. All I had to do was install an app called OB professional on my phone and connect using bluetooth. The setup was super easy and I immediately went into brushing my teeth. I really liked that I was able to see an image of teeth on the app and the more I covered certain areas the more whiter the teeth on the image would become. Furthermore, it detects everytime you move the toothbrush to a different area or angle the toothbrush from inside of the teeth to the outside. It's truly incredible how far technology and this toothbrush has taken us. I was able to select between 7 different modes: daily clean, whiten teeth, tongue cleaning, gum care, sensitive, super sensitive and intense. To cover 16 zones around my mouth it took me about 4 minutes. At 5 minutes the toothbrush automatically would turn off. Also, in the app I'm able to select a reminder for flossing, tongue cleaning, and mouthwash. This toothbrush came with 4 replacement heads, a charging travel case with a cord that connects to the traveling case and a separate magnetic charging stand. When charging the toothbrush the screen shows a bar level and a digital number depicting how much the toothbrush is charged. After so many years brushing my teeth and going to the dentist, who knew I could learn something from a toothbrush like this one?! I was able to customize a color on this toothbrush and while brushing it lets me know based on green light, customized color or red warning color if I'm going too hard on my gums. To protect my gums and teeth further in the future, this is such a helpful feature! Another plus to this toothbrush as I brush my teeth is that it gives me a report at the end. The report shows me how I did on brushing my teeth and if I missed any spots the visible image of the teeth is shown during brushing process and it gives me a percent when I went a bit too hard on the gums to improve for future. It also helps that it's lightweight, water proof, and easy to use around the mouth. The bristles are far from anything I've ever used before. I'm used to long and angled bristles. However, these toothbrush heads are unique as they really work on each and different tooth and angles. When cleaning my tongue it's a very quick process and really does a fabulous job leaving my whole mouth clean. This toothbrush leaves my sparkly white teeth so smooth and clean almost as if I left my dentist's office for a cleaning. I honestly wish I have discovered this toothbrush few years ago when I was going through invisalign treatment as I had to brush my teeth a million times a day. This toothbrush is truly the way to maintain good health and healthy teeth. After using this toothbrush for 2 weeks I've noticed how much whiter my teeth have gotten to be. Forget whitening my teeth, simply brushing my teeth 3 times a day does it! I loved that while using this toothbrush it was not loud and did not wake up my newborn! My young kids have loved watching me use this toothbrush so much that they are requesting for one for them for the holidays! The two things I would improve about this toothbrush is for the traveling case to have a UV light to sanitize the toothbrush and to make room for 2 brush heads for those that love to travel with their significant other and love to share their case. As right now I'm only able to place one toothbrush head in the traveling case. In addition, I would love to see more different colors for this particular toothbrush like purple, royal blue and green. Overall, magnificent electronic toothbrush that I cannot say enough positive things about! Very impressive!

[This review was collected as part of a promotion.] As soon as I receive this package I opened it up it was perfectly packaged easy to assemble I tried it right away. The motion of the brush was great and my teeth felt so clean I love this product and would recommend it to all and it’s even great to travel with.

I had the Oral-B Genius 7000 series and 5000 series for over a decade. I recently gifted the iO Series 8 which was meant to be quieter, more compact and have better battery life. I started having issues with the device after about 6 months. It would randomly switch off even though it showed battery level above 50%. I tried troubleshooting using instructions on their website which didnt help. I eventually sent it in for repairs. I was given a new toothbrush. After about 6 months with the new toothbrush I started experiencing the same issues as the old toothbrush. It would randomly switch off and need charging even though it was charged a few days earlier and the indicator showed more than 50%. Now I'm not getting assistance from Braun/Oral-B as my brush (even though its 6 months old) is no longer under warranty. I would not recommend this brush.

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.

[This review was collected as part of a promotion.] I am in love with this toothbrush. The different cleaning settings is such a neat feature. The pulsating action is gently to the touch but my teeth and gums have never felt cleaner! Highly recommend this brush!

[This review was collected as part of a promotion.] This electric toothbrush is great and I would put it up against any day it’s more expensive competitor. I also really like the different modes and how easy it is to switch between the modes. Nothing bad to say and I would recommend this toothbrush.

[This review was collected as part of a promotion.] Oh! My! Goodness! I'm in love with this toothbrush. I wasn't expecting much but was pleasantly surprised when I started using it. I tried the intense clean and at the end it felt like when I leave the dentist after a cleaning. Pretty powerful little brush. Would definitely recommend and know that you won't be disappointed.

Why would have thought a toothbrush with AI and an app. This toothbrush is amazing and over the top. Best investment ever! As I was reading some of the complaints, all I could do was laugh. These people obviously do not know hire to brush their teeth. This toothbrush makes you feel like you just left the dentist after a good cleaning every time you use it. I love the app, as it lets me know if I missed an area, if I used too much pressure and how long I brushed for. Very cool. It even gives me a happy face when I am done. I hope they come out with a smaller version for kids. That would be perfect for parents who want to teach their kids good brushing skills. Thanks Oral B!!

[This review was collected as part of a promotion.] I have one of these and it works really good. My teeth feel just like I was at the dentist for a cleaning. It works excellent. The charging station is small and does not take a lot of space which is really nice and it comes with a storage for the head. It is easy to hold on to and has a timer on it for how long you should brush your teeth.
