Very hard to assemble due to the very thin sheets. Trying to tek screw the corners together was so hard you get through the first sheet to have the tek screw slip off even with pressure on the other side. The door support instructions show incorrect instructions if you follow them you can't close the doors. I have put two sheds up in the past and this was the hardest to put together. I had myself a fitter and turner a sheet metal worker and mechanical electrical tradesman to help put it together and it took a full day to put together. Customer service and delivery is fantastic just a night mare to put together.
