This product looks great and is very solid. Even before the roof went on there was no wiggle in the structure at all. All parts and pieces were present, no extra trips to the hardware store. The biggest problem we encountered was 2 critical pieces of the roof framing were badly twisted and warped. It took some woodworking experience to coax them into place - not a job for someone without proper tools. That, and the cheap Chinese drill bit shipped with the package snapped the first time I tried to use it.
