This shed came in two large boxes, one of them took both my husband and myself to lift.  There are a LOT of pieces.  Some not labeled. Took the boxes apart, grouped all the items together by coordinating number.  The only issue we had is the screws are not labeled, they are all thrown in the same bag together.. We put the short black screws in the bottom to hold the brackets, when it should have been the longer ones.  Its very hard looking at a 1" photo of a screw to see which one it might be..  
Other than that, no issues.  It took us a little more than 3 hours to put the entire shed together.  
We had a pretty good storm come through town last night, with 25 mph gusts of wind and no issues.
