Purchased and assembled this a few weeks ago to store lawn and garden equipment on a lot.  I was able to assemble it alone in about four hours. Should be much easier with two people. I normally glance at diagrams and jump in. Something told me to read the directions first and its good I did. There are also a few tips in the images that were important but not obvious. The codes markings were not all clear so some guesswork and deduction was required to get the tubing parts in place. I saw a few reviews which noted how the packaging is very heavy and falls apart. I experienced the same. I took a guess how tight to rachet the covers to balance between too loose (excessive flapping) or too tight (stress on the seams). It’s a plus to be able to adjust them. Overall it seems like a good product and design for the money.
