Query: water works

My 2.5 year old son enjoyed playing with this on and off for about 6 months, so was a pretty good purchase. It sticks very well onto our fiberglass tub/shower. I did take a star away because the chutes with the wheels don't turn very well unless they are at the perfect steep angle and the maximum water is flowing. The suction cups are pretty difficult to remove from wall of tub, stick really well, but even with all the removals, not a one broke.
