Liked but stopped holding a charge 1 yr in.

overall the tooth brushes are great, but i expected 1 white and 1 black. i opened the package and was surprised with 2 white instead.

[This review was collected as part of a promotion.] I am In LOVE with this toothbrush! My dentist has even noticed a huge improvement in the health and whiteness of my teeth! The endless smart gadgets ensures that you brush your teeth like a professional, leaving your teeth clean and bright. The brush itself is the just the right size and it’s shape ensures that it reaches every nook and cranny of your teeth without irritating your gums. A light even lets you know when you are brushing too vigorously. The Bluetooth capabilities and app has position detection which helps you perfect your brushing technique. The app shows you how long to spend on each area of the mouth in order to complete the recommended 2 minutes of brushing. The timer is so helpful and it even congratulates you for meeting your goal! After you are done, the coaching feature scores your brushing and shows highlighted areas of your mouth that need improvement! This was my favorite feature and I became very competitive and motivated to improve my technique- I am not joking when I say I look forward to brushing my teeth now! Also, you can find the perfect mode based on your teeth cleaning goals and sensitivity levels - my personal favorite is the whitening mode! The magnetic charging station is so easy to use and the charge lasts for a long time. I love the travel case so I do not have to worry about it breaking it or getting it lost or dirty on trips. I never thought I would be this excited about a toothbrush- it really is a game changer- LOVE IT!

The toothbrush worked great for about 6 months. Now the brush is broken because the magnet inside the handle has come off into the brush head. A tooth brush this expensive should last much longer. Buyer beware. I would not purchase again. I am meticulous about the care of my brush, washing/rinsing both the head and base after every use and storing properly. This is a manufacture defect. Do not buy!

[This review was collected as part of a promotion.] I'm happy with this toothbrush, but one major thing to keep in mind is how fast the battery dies. I've never owned a rechargeable toothbrush before so I was really excited to try the io7. My teeth feel super clean, which I love. Its very user friendly. I love the timer feature. Overall, this is a great device, but I wish the battery did not drain so quickly.

[This review was collected as part of a promotion.] This is a truly impressive toothbrush! Wow. It uses AI technology to make sure you are brushing thoroughly and long enough. It has a timer as well as pressure technology. It’s sleek looking and compact enough to keep on my bathroom counter. Worth the money!

[This review was collected as part of a promotion.] I was a little apprehensive about changing from my normal old fashioned toothbrush, buy using this one I can really feel and see the difference in how clean my teeth are. I also love that I can change the settings to make sure I'm getting exactly what I want out of the experience.

I bought the iO Series 9 a few days ago…and I love it. However, there is no brush head holder and the brush will NOT stand up on it’s own…so not very sanitary if you like to take the brush head off after each use like I do to avoid any mold or mildew between the 2 parts.

[This review was collected as part of a promotion.] I have been using this toothbrush for the past 3 weeks, and it has many features that I enjoy and a couple that I would want to improve. It was very easy to follow the steps required to set up the toothbrush. I like that it has 5 smart modes. I selected and use the “daily clean” mode every day, but it’s nice that I could choose the “intense” mode or “sensitive” mode if needed, as well as “whitening” or “gum care”. One of the first things I did was download the Oral-B app, and I tried multiple times to connect my brush to my phone, but I wasn’t successful, so I can’t comment on the brushing feedback provided by the app. I like that the smart pressure sensor and interactive display provide me with some feedback about my brushing (whether I’m applying too much, too little or just the right amount of pressure and a smiley face to let me know how well I brushed). I like that the display shows me my total brushing time and keeps track of the 30 second intervals for each quadrant of my mouth. I also like that the brush pulsates every 30 seconds to indicate when I should move to the next quadrant of my mouth. It’s also nice that the interactive display tells me the remaining battery charge percentage after every brushing. I find that the brush heads are a little large and bulky in my mouth, especially when I’m brushing toward the back of my mouth. I also wish the brush handle was cradled more by the charger rather than simply being placed on top of the magnetic center. It’s very easy to knock the handle off the charger. Overall, I think this is a great, modern, unique and convenient toothbrush.

[This review was collected as part of a promotion.] I have been using this toothbrush for about three weeks now. It truly is fantastic, it has 5 smart modes. It will tell you how long you brushed. It tells you if your not brushing hard enough. It tells you if your brushing too hard. Ive never used an electric toothbrush before. But I can tell such a difference in how my teeth feel, so clean!.
