does anybody have a sense of whether the FIT is that much better than the other two? I have it in my cart because "ooh, deep discount" and "SHINY!!" but if it's really pretty much the same I may go with one of the others.
there's also a crapton of brush heads on sale as well...
I have the Mia 1 and I've never felt the need for another speed. I haven't looked into the Fit though so I can't really compare. The Radiant brush head is awesome if that's on sale though.
