Simple to assemble but the roof members were too short and not fitted to assemble square to the vertical panels. I reported this to Shire over the phone and was told that the parts department would be informed. Nobody called, nobody cares. I finished assembling it, introduced additional roof stiffeners because the feather edge boarding was too flimsy and I’m reasonably happy with the result. All these companies are the same. Customer Service is any oxymoron. Once they have your money, they aren’t really interested. Quality is average for the money. It’ll do for now, just don’t expect too much if you have any problems
