Some disappointment. Many of pre drilled holes were too small for screws. The small screws on roof panels too long, had a lot of trouble fitting them in tracts. We tried to do it ourselves but ended up costing me to hire someone, he was the one who figured out mentioned problems and had to redrill holes and. Cut screws down
 I slso think the poles could be stronger. Once it was up im basically happy with it.   It cost me an extra $100  for hired help. And a lot of frustration and extra hours of time because of mentioned problems. Item too big to think about returning.
