Is it the sturdiest tool shed? No. But after searching high and low for a shed that would fit our 2' x 2' space, this was the best thing we found. 

per all the other reviews - the 3' x 2' is the exterior dimensions which has a roof that has overhangs (which is a good thing) and stabilizing rackets on the bottom. 

Regarding no pilot holes - there were pilot holes for 85% of the nails. The ones that didn't have pilot holes were minimal, and wherever you drilled it had no impact on the structural integrity. And to be honest, the wood was so soft (reminded me of the wood in the middle of your popsicle), didn't need pre-drilled or pilot holes on most of it. 

Hopefully it holds up over time. 

The other thing we really liked about it is, it's not a particularly tall shed, so it was nice that the divider below the top section was movable. We had to move most of the slats so the full size shoves could fit.
