The Colgate 360 is a good toothbrush. I'm not sure where we got it. (We don't normally buy such fancy toothbrushes. It goes for $4 at CVS.)
Two things of note...
a) I was amused at how the brush design copies the heads of electric toothbrushes.
b) The gel-bristle back of the head feels great in the mouth. I'm not sure why, but it's an interesting sensation. It's supposed to be a tongue cleaner, but I have never used it that way. My tongue is generally pretty clean.
Silly little video here.
