Review (5/5): Works great!
Not much to rate here. It either works or doesn't. Mine works great. I guess if I had one complaint, it would be nice if I can pump one time and get a decent amount. I need to pump 3 times to get just enough to swish around. And for those with big mouths, you would probably need 5 or 6 pumps. Good exercise. Be careful though, the pump has some power and it might splash out and leave marks on the wall/mirror behind it.
