My son bought one and he is not a DIYer and put it up himself in under 3 hours. My daughter bought one the same and asked if I could help. After starting at lunch time, we had to stop 5 hours later as ran out of light. The parts do not line up correctly, the panels are too small, and the next day took us another 6 hours and even then, the door does not close or fit to the frame. I cannot see where the quality control is to this. With a lot of homemade adjustment, I got it all together although the door still won't fit the frame so I will have to trim the plastic to get it to fit. Totally disappointed. If I knew it was going to be like this, I would have bought a wooden shed instead. I would rather have to treat it annually than have this which looks a bit odd.
