My sons (11 & 13 yr olds) lost interest in this thing in about a day... When I first got it they were both really excited and ran quickly to the top! But after they came in to eat lunch (at that moment they were still excited and couldn’t wait to go back out and play with it some more) and went back out they kicked it over (it was intentional too) and didn’t care for it anymore! :( Returned!!! Would not purchase again! NeiTher would I recommend!!!!
