3.5 stars. I liked the price and impressed with the design and materials. Assembly was easy. The 5 and 3 year old (both under 50lb) loved it. But as others have pointed out its flaws. I think with some future modifications it will be 4.5 stars. The curtain won't stay on but that's not too major. The biggest thing is the handle design. Especially when the kids rely on it after getting tired or they get going pretty good. So far ours has just lost the left screw just above the tightening nut. Perhaps some locking type pins. The feet have held up but I have noticed that if one of the kids bounces off center really hard it will want to slide a bit on tile. Probably not a thought in the design.
