The one good thing? They're inexpensive.
I still can't figure out the toothbrush with three heads, the design didn't make sense to me. If my dog could speak, I'm sure she would ask: "Why do you stick this weird thing in my mouth? Take it out!"<br /><br />I wish there is a video explaining the design of those three heads, and how to use it properly.
