I was impressed with the shipping speed, sturdiness, ease of assembly. My 12 year old son loved the design and this fit the bill of what he wanted entirely. One thing I didn't expect was an extra set of hands included to put it together. THERE WAS A COCKROACH STOWAWAY in the box! We were so excited it had arrived, we tore open the box to find a 2 inch long live cockroach below all the parts. The kids and I were thoroughly grossed out. Of course it could have snuck in during shipment, but I don't know. It was off putting and I'm having a hard time getting past it. As far as the product itself, it was well worth the money. 3/5 for that.
