The canopy was easy to assemble. Once its put together it is taller than originally expected and there is plenty of room to walk around the stored vehicle. The zippers on the front and back entrances work well. Really the only thing is that I wish there had been side or back braces to keep the garage from wracking, not just the flimsy ropes that came with the garage. We added X-bracing on the sides and one in back to make sure that in a wind storm the garage would not be ruined. It was a simple fix, but something like that should have been supplied in the original purchase. Overall, sturdy, good buy, does what it says it will.
