Great Quality Replacement Heads at a Better Value!

These replacement brush heads compatible with Oral-B iO (2–10 & Deep Clean) have been fantastic. They snap on securely and feel just like the originals — very smooth, thorough cleaning every time. I’ve noticed my teeth feel just as clean as when I use the brand-name heads, and the bristles are holding up well after multiple uses without fraying. The set of 6 in black looks sleek and lasts a good while before needing a swap. They fit perfectly on my iO handle and the performance has been consistent across all of them. Great value compared to the pricey OEM heads! Highly recommend if you want reliable, effective replacement brush heads without the high cost. Read more

Cheap toothbrush head

Cheaply made brush heads. Little to no power transfer when you apply any sort of pressure. The head regularly stalls out and you have to revert to manually brushing. These are going straight in the trash Read more

Won't get again

Liked how many there were, not sure they actually fit. Do not fully insert onto the toothbrush, and have a very short life span (~2months) Read more

Bristles

If you have had surgery on your tongue start very slowly and carefully.

The brushes are rated gentle but just a little harsh for me. Otherwise they are good. Price seemed fair and it works well. Cheri M. Read more

Fits well. Works well.

Fits well. Works well. Little to no difference between these and “official” Oral-B replacement brushes. Read more

Doesn’t work well

Spend the money and get the name brand, going from the actual head that comes with the brush to these is very noticeable. Not worth the money you save since they don’t work the same. Read more
