Review (1/5): Save Your Money
I purchased this at a local drugstore. I did not have the suction problems others described - quite the opposite. I put it on my tub floor and when I went to throw it out, it was quite a fight to un-suction it. Why did I throw it out? Two reasons. First - I don't know why it didn't occur to me, but I'm super ticklish on the under side of my foot between the ball and heel. Washcloths and those mesh-type bath sponges are fine, but bristles - forget about it. This made this akin to a torture device. Second - I *might* have been able to tolerate the torture if it had actually cleaned my foot. It did nothing even close to clean it.
So, in short, doesn't clean your feet and it's torture if you are ticklish. Garbage.
