Inadequate Substitute
This product is an inadequate substitute for authentic Oral B IO brush heads. Just save up your money to buy the authentic brush head replacement! Read more
Stiff
These are very stiff bristles. Otherwise, they are compatible with the Oral B IO TOOTHBRUSHES. Read more
Oral B Io Toothbrush Heads
These fit perfectly and work nicely! Make sure you are ordering these for your zip toothbrush as they are specific to just this kind. They are high quality and don’t need to be replaced as often as other toothbrush heads I’ve used in the past. Definitely recommend and the price is just as satisfying Read more
