[This review was collected as part of a promotion.] I was excited to try this toothbrush. Upon receiving it, I tried to charge it, and it wouldn't charge. After many attempts to get the toothbrush to charge, I was unable to. I would not recommend this toothbrush based on this alone.

[This review was collected as part of a promotion.] I gifted this product to my husband and he after the first time using it stated that his teeth have never felt so clean. He absolutely loves this toothbrush, and I believe it works so good. This toothbrush isn’t loud at all and the battery life seems to be really good. I will definitely be purchasing myself one because it is so nice.

[This review was collected as part of a promotion.] I really wanted to love this electric toothbrush, but unfortunately, it's just not for me. It vibrates too hard, even on the lowest setting. But that's just a matter of preference. It did clean my teeth really well, though.

[This review was collected as part of a promotion.] The toothbrush is a bit loud, but it cleans well. I wish the head of it was a bit thinner, so I could get to my back teeth a bit better. The price is good, and the batter power is great as well. Would recommend.

[This review was collected as part of a promotion.] It's gentle on my gumline, and does a great job cleaning my teeth. Much more gentle than the previous model, while being more quiet! Its sleek looking, battery life lasts for over a week. Charging time is less then hr to charge all the way.

[This review was collected as part of a promotion.] I'm using the Oral-B iO Series 2 rechargeable toothbrush and it's great! It cleans my teeth really well and makes them feel super smooth. I like how gentle it is on my gums but still powerful. The brush is easy to use, and I don’t have to worry about changing batteries because I just charge it. The timer helps me brush for the right amount of time. It looks nice too. I'm really happy with it!

A few years ago My dentist recommended I should get an electric toothbrush Sonicare. I have been using it for a little over two years. My new dentist recommended to get an Oral B. So I recently purchased a io series 2. This unit is horrible, it says two minute timer. It does not shut off after two minutes not like my Sonicare. It just gives an extra vibration. vs the vibration it gives off during 30 sec quadrants. The neck of the head is way thicker than the Sonicare. And after ever use I have to pull off the head and clean it out I do not have to do that with my Sonicare. This unit was a waste of money I just hate it.

[This review was collected as part of a promotion.] I have used an electric toothbrush for years but this new @oralb IO series 2 is really an improvement over my current brush. Thanks @influenster for another great claim!!! First thing is I love the color. It is so nice to have a black brush. It works so well at really cleaning your teeth. It isn’t loud, bulky and the charge really lasts. It has 3 cleaning settings. I like it so much that I am going to buy a matching one for my husband. The cost is in line with the quality!

[This review was collected as part of a promotion.] This toothbrush is a wonderful way to clean my teeth in a way regular brushing can’t do. The ergonomic design ducts nicely in my hand. I was worried that the bristles were too small but the way this spins I have no reservations. I am yet to charge this product fully because it can e charged I’ve used it for 5 + days and no need to recharge. I love how small the charging doc is, it tasked up minimal place on my sink and I can put it away when I’m done charging. There is a low hum sound when the toothbrush is in use, but it’s not overwhelmingly loud minimal noise level. This is a great toothbrush leaves my teeth feeling clean and my mouth refreshed.

[This review was collected as part of a promotion.] This Toothbrush is a game changer! I feel like my teeth always get so clean after using this. I love that this is rechargeable, and does not run on batteries. The replacement heads are also fairly inexpensive and easy to find at my local stores.
