So far I am happy with the shed. I built a wood base elevated off of the ground and then assembled the shed on top of that. If I could so anything differently, I would have had a concrete slab poured instead of constructing the wood base. Even though I leveled the base, I think it began to settle after a few days and the shed wasn't assembled on a perfectly level surface. One thing I will say is that if you try and put this shed together on a slightly non-level base, it will be a beast to get all of the panels and screws to lineup. It took me about 18 hours to put this together and that's with my 16 year old daughter helping me. But once completed, it really is nice. I do have concerns about the strength of the screws as many of them do not seem snug.
