I bought this shed over a year ago.  I was able to assemble the shed mostly by myself, needing help from my neighbor when it got time to put the roof on.  Took two days, including my constructing a wooden foundation.  All the parts were labeled very well and the instructions are clear.  I had a small problem with the doors not aligning but my neighbor and I used a jack to lift one side of the shed and placed a couple of additional wood blocks to make it square.  No problems with leaking at all.  Very well made and maintenance free.
