The end product was sturdy and my 3 grand boys, who can destroy a Tonka truck with a rubber hammer, love it. With that said, this thing required myself and two others to put together. The instructions were somewhat confusing. I found a YouTube video where two gentlemen were putting one together exactly like this one (different color) and I followed it step by step. Still wasn’t sure we were doing it correctly until at the end when it fell into place. It’s quite large so be mindful of where you want to place it, easily movable though.
