Just purchased 2 this weekend, by dentist recommendation. Cleans wonderfully, BUT I have been using a Sonicare for years and was used to purchasing a smaller size brush head to reach the back teeth. That option does not exist with Oral B. Also no cap for the toothbrush head is available, nor does the series iO brush head stand up on its own due to the slant of the base. Not sure whether I will be keeping it.

[This review was collected as part of a promotion.] I tried this product for the first time and absolutely love it. It cleans my teeth so well they feel great after. My gums also get a great massage and look.so much healthier. I would definitely recommend to any one looking for a new electric tooth brush.

[This review was collected as part of a promotion.] I have been using an Oral B electric toothbrush for years now, I've had a couple different models and they were both great. I really like this brush head set for them. They are firm enough that it really feels like your teeth are getting really clean. I always do the extra 30 seconds just on my front teeth as well and it feels great after.

[This review was collected as part of a promotion.] These Oral-B iO Series Ultimate Clean Electric Toothbrush Replacement Brush Heads are definitely a bit on the expensive side, but they are the genuine, original Oral-B replacement heads. They fit perfectly and maintain the high cleaning performance of the iO toothbrush. If you want to keep your iO performing at its best, these are the ones to get.

[This review was collected as part of a promotion.] I love this toothbrush head. It makes my teeth and gums feel cleaner then anything I have ever used. I feel like it is scrubbing my tears but not to hard and it is massaging my gums, but ina good way. My teeth feel so clean and healthy.

[This review was collected as part of a promotion.] Very efficient cleaning power. Left my teeth feeling clean and polished. Bristles are soft and gentle yet firm to remove plaque. The circular design allows you to reach difficult spaces. These replacement heads are good value for the money, I recommend.

[This review was collected as part of a promotion.] I am very impressed with how clean my teeth felt after my very first brushing. The shape of the brush head allows each tooth to get thoroughly cleaned. It also felt like my gums were getting a great massage. Very impressed. If there was anything I would change it would be these two things: 1. Having a flat surface on the bottom of the replacement head. This really bugs me as I like to stand the brush head to dry in my medicine cabinet. I'm unable to do this as it's angled and have to lie it down which isn't the best option. You may ask why not just leave it on? Well, there's several of us who use it, so that's not an option. 2. Having a cap to cover the brush head in between uses. Yes, it's kept in my medicine cabinet, but it has fallen on the floor so having that extra coverage would be a great feature. .

[This review was collected as part of a promotion.] I'm impressed with the way this toothbrush actually makes my teeth feel and look. I have had a lot of toothbrushes over the years but this one really does what it says it will. Well be keeping stocked up on it.

[This review was collected as part of a promotion.] I am so glad I got to try this brush out, it cleans my teeth real well and, feels better then most brushes. I really recommend these brushes especially if you want something to help get the places that are tough to get through.

[This review was collected as part of a promotion.] I have very tender gums and at first I was a little wary to use these brushes. I am so happy that, not only did they not tear up my gums, they made made my teeth feel squeaky clean. The brushes did very well in getting in between my teeth and leaving my mouth feel refreshed.
