Very sturdy and seemingly well made for ease of assembly. Goes together perfectly and looks really cool too
Engine is well build and fun to play with. Kids love messing with it. I have bought at least 10 items from this company, and all are quality constructed.
Very easy to build. Very good material. Thanks
