They are toothbrush heads. They work as you would expect them to.

The Brush and the Floss features conducts an excellent cleaning process on my teeth.

Works very well. Worth the purchase to have a very clean mouth, teeth and gums.

I like to have extras on hand, I haven't used them yet but looking forward too it.

This waterpik gets my teeth super clean. My mouth feels great after using. Great product!

Second set of brushes works as good as the first set

Bristles too soft. Excellent, tight fit to body. kkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkk

It works wonderful. It gets more food out from between my teeth after even flossing and bushing.

Like the larger head on the tooth brush gets gums as well as teeth

I love my fusion waterpic unit. Just like having my teeth cleaned at the dentist.
