Doesn't really work - too soft
You'd be better off with a washcloth.  The product is not defective, but the bristles are way too soft and you don't get that scrubbing sensation you'd get from a loofah or a Salux nylon (Japanese) washcloth.  It may work better on my dog?  So for me, it's back to a Salux and a regular washcloth.
