Review (1/5): Ridiculous!!!!  Don't waste your money.
The apparatus does not adhere securely to the shower floor and, therefore, slides all over the place when sliding your foot in and out - impossible to use the built in (mine was cracked on arrival) pumice stone. Total waste of money for this cheap piece of C**P. I'll be buying a brush with an extended handle. I wish I could give less than one star!
