Horrible squeak on clean hair, otherwise great
I'd love to give this a higher rating, but the noise it makes when your hair is clean is deafening.  It's this horrible deep pitched squeaking that resonates in your head.  Too bad because otherwise it works great and the pricing is right.  I guess you could call it a "feature" as it lets you know when the soap is gone, but man is it loud.
Rating: 3 stars
