Put together in one afternoon by 3 older adults in 60's.  Great product, went up easily with the simple instructions.  One tip, if you do use a power tool to put in the screws, do not use it for the vent fabric, it will tear it up!  But if you follow the instructions this won't happen because they tell you not to use a power tool.  Super nice and roomy, perfect for my garden tools, and 2 bikes and many camp chairs and vollyball net.  Now I can get to my tools, bikes and supplies without going crazy fighting through the jumbled mess I had before in just one shed.  The hardest part of putting this up was the foundation which we built by leveling the ground and putting down an area of cinder blocks.
