Clairsonics- Yay or Nay?

Is it really that much different from the powered cleansing brush that
Olay has out? I went to the web site and read what they had to say about
it and I realize it says its sonic, but can it really do that much more
then the Olay brush, or other brushes like it can? I have the Olay
cleansing system and my brush does a great job and it costs a lot less
then this one does. It just sounds to me like they added the word sonic
to make it sound better and so they could give it this high end price
tag. If I were you Alex I'd be leery of spending that much money on it
unless you could return it, witch you probably can't. I think you'd be
better off giving the Olay brush a try first, but that just my opinion.
