The shed went together quite well. The assembly hardware was bagged and labeled individually for each step. There were no shortages. In fact there were extra screws and such. The instructions were very concise. It pays to pay attention to the fine detail & follow them exactly. I got a little ahead of myself at one point and had to backtrack to correct my mistake. The only recommendation I can make for an improvement in the instructions is a little larger pictures in the detail sections. Not too bad though. 
As for the quality of the shed, it certainly seems sturdy enough (for a plastic shed) & well thought out but I don't yet have the test of time. It's overall quality and features were at least as good or usually better than the other 3 or 4 top brands that I looked at. 
There really are no negatives here so I would definitely recommend this shed.
