My dentist insisted I get an Oral B IO because I have crowded teeth and I would get a better clean. I ditched my sonicare for this toothbrush and I regret it deeply. I just got through picking an inch thick layer of black mold from the toothbrush connector. It is so poorly designed to have that issue. I'm mortified.

5 stars for teeth-cleaning ability! I changed to Oral B at the recommendation of my periodontist as I have a history of gum recession. I've enjoyed the teeth-cleaning features of this brush. Unfortunately, I've had recurring issues with keeping this toothbrush clean. After just 2 months of regular use I began to detect a mildewy smell. The design, while sleek, tends to keep water inside - both the brush head and the handle head. I replace my brush head regularly but that does not solve the issue of the mold inside the handle head. I've now had the brush for 5 months and clean it every day according to Oral B instructional videos (disassemble and thoroughly rinse and dry both parts, allow to dry separately overnight); however, this still hasn't solved the problem. It's nearly impossible to dry all the crevices out completely after rinsing, and the brush head can't stand up on its own to dry overnight. I've soaked it in vinegar, denture cleaner, soap, etc., and still struggled to get rid of the smell. I don't really want to clean my teeth with something that molds easily - and I'm really bummed about it. I might switch to a different toothbrush model that doesn't have so many crevices.

Poor quality. It lasted less than a year, and unfortunately I didn't keep my receipt. It kept a charge for a few months, but then wouldn't recharge. Complete junk!

[This review was collected as part of a promotion.] I'm pretty impressed with this product, Ive had electric toothbrushes in the past that I didn't like at all. They were too loud or just vibrated the heck out of you mouth causing irritation. Or they didn't get your teeth clean. But this brush did such a good job with the different settings. The instructions recommended it on the sensitive setting to start. Which is great to have the information prior to using. My teeth feel so smooth and clean. It took away built up and stains in just one use. It's also aesthetically pleasing and cute. It was easy to set up and charge. The heads are easy to replace. Over all I recommend this tooth brush.

[This review was collected as part of a promotion.] The cleaning performance is outstanding it has 3 levels just like going to the dentist for a dental cleaning routine, the battery life is great and live up to Oral B reputation. The noise level is low and smooth, the design is cute and very interesting. Overall, this is by far my favorite toothbrush!!

[This review was collected as part of a promotion.] Oral-B will always be my number one electric toothbrush. I have had a couple different ones but so far iO2 series has been the most powerful and reliable one. And the best part is that it does not make the annoying sound that most electric toothbrushes do. Battery lasts longer than normal and it charges pretty quickly

[This review was collected as part of a promotion.] This toothbrush works as it says. I can't speak on how well it does for natural teeth, because I have dentures... but it does leave them feeling clean. It also works well for my gums. Noise isn't bad at all, unlike the electric toothbrushes of the past.

[This review was collected as part of a promotion.] I received this product for free for testing purposes from Influenster to try in exchange for my honest review of the toothbrush. I am a huge fan of this toothbrush! It cleans so well and just really works amazingly!

[This review was collected as part of a promotion.] Great gift. Very nice and stylish packaging. The design of the brush is very simple, the color is black. The handle is comfortable. It is suitable for both adults and children. The battery lasts a long time, it recharges quickly and holds well. I gave this toothbrush to my daughter because she has not yet fully understood the true importance of brushing her teeth. It has a built in 2 minute timer that helps her know when to change areas of her mouth by vibrating every 30 seconds. It rotates so that all teeth are brushed and it reaches even the smallest areas of the mouth!! It is very quiet compared to other brands I have tried in the past. It has enough power so it does not stop if you apply light pressure! Brushing your teeth is great. The price matches the quality! Definitely recommend!!

[This review was collected as part of a promotion.] I've never had one of these electric toothbrushes before but my grandma swears by them so when this came up I Decided to give it a try. I like it. It's simple and sleek. I like the weight of it. It did a good job cleaning my teeth. I also like it that it has multiple settings and the timer function.
