This shed is nice looking and seems sturdy. It took three of us most of a day to put it together (excluding breaks, maybe 10 or 11 hours). 
The floor isn't very strong or tough, but I didn't expect it to be.
The roof was the only issue we had. The parts had a hard time lining up with the trusses, especially the main center truss. That caused some trouble with having the the different roof panels fit together. The result meant that there were gaps between the top roof panels and the side ones because we couldn't get them to screw together. We had to put the screws through from the top of the roof to make it work. It hasn't really affected anything, and I'm still happy with it. 
I appreciated the manufacturer's videos that showed how to re-level the shed to allow the doors to close properly since I had an issue with one being way too high when we were done.
Overall, a decent product with good space inside. I liked the shelves and hooks that  are with it, too.
