Good build quality but a couple issues with our particular set. Delivery was on time and as scheduled, good communication there. There was some taped up patches on our second box, and upon opening, it seems there was a little damage for one of the roof panels in transit (I don't think it was the fellows who dropped it at my house). The plastic wasn't totally cracked thru, so we decided to work with it. Additionally, we received (2) 75-count packages of the main screws when we should have gotten (1) 75-count and (1) 125 count. We came up about 30 screws shy but we're close to completion so my husband ran to the local hardware shop to pick some up. A little annoying, but not deal breakers.
