Overall I'm pleased with this shed being as how it is roughly 1/4 the price of a wood shed at the same size. Yes you have to make sure you build your base level and square. I spent 2 days on the base alone, and do no eye ball, be precise. Other than that it's sturdy enough for me to like, but definately not as sturdy as a wood shed. Would I recommend this? absolutely due to the price and looks. I've only had one problem, it did leak at the top near the top vertice. But some silicone sealant it was good to go. I even put up a pegboard, and build my own wood shelves for less than 40bucks. Great buy in my opinion.
