I purchased the brown color 9x4 metal storage shed. Based on other reviews, I knew the assembly would be difficult. I took my time, built a base for the shed and added a floor (as well as a lock). Assembly wasn't as bad as I thought, but you really need to study the pictures (I used a magnifying glass to see which way the parts were oriented and screw holes). I had to rotate the roof panels since the center holes didn't line up with center support. It took me a while to determine how the center rail side brackets should attach. All in all, I only re-drilled about 4 holes, mostly for the roof edge pieces where panels overlap. I was very disappointed that the wall and door panels were different colors (some light brown, others an orangey brown), not like the advertised pictures. The mid-wall support pieces were supposed to be pre-drilled metal pieces, but I had un-drilled plastic tubes. The saving grace was the price.
