Was disappointed that these weren’t in the store. I spent over $100 in the store and still had to come up with another $10 so I could get my free delivery

These brushes do not last a reasonable amount of time. I’m actually thinking they are defective with the colored bristles fading in the matter of 1-2 weeks. The unit itself is ok, way too slippery!!!! Poorly designed!

I won't be using these until the ones that come with the iO wear out but the ones that came with the devices work great so I expect the same from these. They are a little pricey.

These brushes are refills for an electric brush that I already had. This is the first time I was able to replace the brushes without ordering them. The brush has been more effective than any other brush I have ever tried.

Love these. They get in all the places I need to clean my teeth

Great cleaning, but thick brush shaft causes a lot of drooling. Also wish the brush head came with a cover.

Needed these replacements offer our Oral B IO toothbrushes. Definitely leave you with a clean mouth!

It was an easy choice to buy a 6pack of replacement heads at Sam’s when competitor's charge $30+ for just 2.

Great price but rated 4/5 because I wish it would come in all black and not a mix of black and white. My toothbrush is black.

These new Oral B up tooth brushes are the best, they actually do a better job of cleaning your teeth than any I have used.
