This shed is well built including the trusses, walls, and floor.  Each individual part is well made and for the most part fits together very well.  It took my wife and I about 7 hours to build and the result was worth the effort and price.  The most difficult part is the skylight/roof components which has way too many parts that have to fit together while working over your head.  The design is a bit strange and was quite challenging to align.  It should be simply 2 pieces combining the skylight and roof component pre-formed together from the factory rather than a bunch of separate pieces.  Pictures in the instructions are also small and hard to see.  Overall happy though.
