Love this toothbrush! Its like the dentists in relation to vibration and function , although I am not saying its a substitute for a good cleaning! It lights up to make sure you are using the correct amount of pressure , stays charged for 10-14 days and even shows a smiley face, Sad face Or frown on the handle as To whether you are brushing long enough! I would definitely recommend this and Walmart had the best deal! Its not the newest version but I didnt feel I needed the extra gizmos

The reason I purchased this model, even though I have another expensive Oral B toothbrush, was because I wanted a charging travel case. I was disappointed to find that instead of USB-C charging port, the case comes with a special plug and it's fitted for 110V. So in order to take this toothbrush abroad I need to bring this bulky plug AND an adapter for a different voltage. Ugh.

I purchased a toothbrush two months ago and while I can’t say that it has cleaned my teeth thoroughly as well as prevented tartar around my gums. I only SJgave it three stars because the brush heads are too big for my mouth, causing me to gag as well as the battery life. If the toothbrush is not in an upright position, it never goes to sleep if it’s laying down or if you continuously open up your drawer, it will still be on.

Liked but stopped holding a charge 1 yr in.

Battery won't hold after usages. Had it serviced under warranty again same problem. Won't recommend

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 can't believe there's a toothbrush out there that's better than sonicare. My teeth and gums feel super clean after use. The unit itself is very well made. It has a nice solid weight to it. I love the features that let me know if I'm applying the correct pressure or not. And even though I'm an adult it makes me feel good seeing the little smiley face on the panel that lets me know I did a good job. I like the shape of the brush head. I feel like it really gets in there. It's very user friendly and I like being able to change the settings whenever I want. Most days I use the white and you really can see a difference. My only minor gripe is I wish the brush heads came with a cover. I highly recommend this toothbrush. You won't be disappointed.

[This review was collected as part of a promotion.] As a long time electric toothbrush user, I was very surprised and happy with the quality of the i07 toothbrush. I really like all the visual feedback this toothbrush gives. Additionally, it can be a little awkward given that you need to take the toothbrush out of your mouth to view the data. Regardless, I am a fan! It also helps prevent you from brushing to hard. Which I like because I am always worried about damaging my gums. This brush has a bunch of brushing modes for you to select based on your preferences. I still need to understand some of these differences. I know it’s pretty hard to get jazzed up about a toothbrush, but this product seems to do a great job keeping your teeth healthy.

[This review was collected as part of a promotion.] I got this iO9 Series black Onyx electric toothbrush. At first I was like what is this and how do I use it? It doesn't have instructions saying what some things are even. But after I actually used it I loved it. I love that it has lights and you can set your base color. It flashes red when I brushed too fast and green when I brush just right. This toothbrush is awesome. It made my teeth feel clean and stayed fresh.

I tried this at CES a few months ago. It is amazing and I couldn't wait to get it for myself. I always considered myself as a good brusher-but with this iO brush, it's surprising how much cleaner my mouth feels. It's super smooth, and a lot less high pitched 'mosquito buzzing' of my old brush. The ability to real time track how I'm brushing-that's a cool gamification. Brushing my teeth is less of a chore. One thing I didn't know at the beginning was that you should go tooth to tooth, and let the brush do the work-that's my helpful tip to future buyers!! I highly recommend iO!
