All boxes arrived together, one day early.  Nothing missing, nothing broken. Quality of material seems good.  Instructions are clear if you study them. Page 17 is confusing, should substitute inset # with screw #.
      Additional tools:  Drill driver, 2 Drift pins, Cellophane tape, Ratchet wrench,  Expendable Allen wrenches, (cut off short end, use long end in drill driver).
      Hints:  Put 80 plastic parts 'Z' on roof panels first and tape them in place (they fall off faster than they go on).  Do not tighten parts 'B1 and C1' until the roof is complete.  When installing roof panels, apply as many fasteners as possible before tightening any of them, use drift pins to align holes.
It took 2 of us 2 long days to build on a 12' X 12' deck + several hours to sort, identify, inspect & count everything.   Very satisfied.
