I know these are technically for kids, but they happen to be my favorite toothbrush. I have a small mouth and sometimes have trouble finding adult toothbrushes with compact heads, these are absolutely perfect for my needs! I wouldn't hesitate to recommend them for anyone looking for a compact toothbrush head.
Both of my sons, 2 and 5, love these toothbrushes. They are easy to grip and the heads are small enough to fit into the 2-yr-old's mouth. The bristles are super soft. The only downside is that they wear out pretty quickly, especially if your kids like to bite down on their toothbrush like mine do. They last about 4 weeks, at most, in our case.
