Review (2/5): Not really compatible
Yes, it fits on my Clarisonic Pro, but it doesn't go through the proper cycles. The first two twenty second cycles are normal, then the last two are the same speed as the first two.
The other thing that is different is it seems to absorb whatever product I put on it, liquid soap, facial milk, it doesn't seem to make a difference! I should have sent it back, but it was my second time ordering this type of product (did send the first one back), lazy my bad!
