Review (1/5): Weird
Soap just runs right off. Now sure how it's actually cleaning when you get it a tiny bit wet and the soap just disappears. After trying to use it to scrub and only succeeding in making squeaking noises as the soap goes down the drain, I tried just using the massaging side and it felt like when you ask your spouse for a back massage and your spouse unenthusiastically rubs your back lightly for a minute before giving up and trying to make it into sexy time. So... Not a massage.
In the end it has turned into a great tug of war toy for my puppy.
