The Sisal Sponge is good however the Scrub Exfoliating Star is disappointing. Not easy to use I'm sad to say, as you end up using more shower gel product to get a good lather. Also it sheds which isn't nice when you are washing.
Brilliant concept, reality much different. When using in the shower it sheds thousands of little hairs that fill up the waste trap, blocking the water and resulting in it having to be cleaned out after every use.
