My kids (7 and 4) love it! Instructions to set it up were fairly straightforward. My only knock so far is about the supplies.  The instruction manual says it is supposed to come with 56 washers. But that is crossed out and has 36 written instead. Sure enough, I was 20 washers short.  Not sure why they would do that. I see from another review that this happened to other people too. So be prepared to go buy washers. It is also supposed to come with lock nuts, but only half of mine were lock nuts. The others were just regular nuts. Hopefully they stay tight. Overall I'm happy with the purchase though.
