I read the reviews on this shed extensively before I purchased it.  I set it up on my patio in my backyard.  I cant give an exact time it would take to assemble nonstop;  rain slowed my progress.  Now, I am very surprised at the finished product.  I was a little concerned when I opened the box and examined the thickness of the walls.  However, after finishing assembly, the shed is great.  I have received quite a bit of rain since the assembly of this shed.  The inside of the shed has remained dry!!  This is a great product for the price and assembly wasn't too bad.  I suggest having a helper when doing the assembly, but it can be done solo.  If you want to go solo at it, I suggest having some sturdy objects around to prop up the walls during the early stages of assembly.  This shed.....I say go for it!
