I have never left a negative review ever, but this shed was horrible. First the shipping all the corners of the sheets came in damaged ok sure I can blame the FedEx. However, there was so many problems with the premade holes on the sheets I just couldn't overlook half of the holes on the sheets where larger than the screws given making them useless.  I am going to ask for a refund and I don't recommend it. There's just too many problems to list for this product. It's funny how many positive reviews there where for this product too it was mainly the reason, I bought it. Maybe I just got the bad one of the bunch.
