[This review was collected as part of a promotion.] I bought this about a month ago to use as my replacement for my teeth cleaning unit. They do a good average good job. I did enjoy using them but not as much as my other unit though. Could be better then are.

[This review was collected as part of a promotion.] I tried gentle care brush heads They worked pretty good for me . They are very gentle on my teeth and gums and did a good job cleaning my mouth .I would probably buy again Really good product for someone with sensitive teeth and gums

[This review was collected as part of a promotion.] These work ok. Your teeth feel pretty clean after using them. They are hard to put on (for them to stay on and work right). I prefer a stiffer feeling brush in order to make my mouth feel clean and crisp.

[This review was collected as part of a promotion.] I didn’t pay close attention and thought I could use this brush with my existing Oral-B brush base. They are not compatible! I have to blame this mistake on myself since it says it on the brush’s box.

I bought s black base but am finding no black gentle care replacement brush head. Disappointed.

[This review was collected as part of a promotion.] Very nice gentle round replacement brushes that offer gentle vibrations! This one isn’t as versatile because it only fits the oral b IO series where most of the other brushes can be used on a variety of models! Me, my husband and my son all have different models so I was the only one that could try it! It does come with two which is nice and they seem to last a good while ! I prefer a medium to firm brush but this did make my teeth feel pretty clean, but if you have sore gums this might be a great choice for you!

[This review was collected as part of a promotion.] I don't have an iO toothbrush so I was unable to use this with the toothbrush. However it seems well made and the bristles are not too hard or too soft. The mechanics of the replacement head are also loose which means it seems like it would allow the head to provides more revs per second.

[This review was collected as part of a promotion.] I’ve always enjoyed this company and what they give to the public. I’m very happy with these replacement brushes. They work well and have never let me down. They get the job down the first time of use

A great brush, not cool finding out for 4 more you can get 2 extra heads on a mazon.... 35 instead of 30. Kids in braces needs them so what do you do though.
