I got my shed about a month ago and I can't be happier. I built it on a concrete slab and it went together as easy as I was told. I do recommend taking the time to remove all the extra flashing in areas that will join together for a better fit but the assembly is easy and straightforward. By putting all the small "sub-assemblies" together ahead of the build you will save time and make the job much easier. I found the instructions easy to follow and the videos that are available to watch are a big help. Would I buy this again? You bet I would and after a lot of rain in our area the building has remained dry! I would recommend this highly!
