Review title is Great idea, poor execution. If only it worked as designed. [SEP] Well, it’s just like a mini mud buster, the manual spin feature is cool & an awesome idea, but unfortunately if you get your dogs paw into the cup and hit the button, it’s not going to really scrub all inside between the pads or whatever. So I just end up rubbing his paw up and down against the silicone. Also as you spin the water leaks right out of the cup leaving a mess. Great idea, poor execution.
