Overall, you'd have to color me impressed. The joints were smooth and without any burrs, and the fittings/screws were quality. Loving the rubbery stretchiness of the plastic film. It seems thicker than the regular 6mil UV greenhouse film from the hardware store. We've been blasting it with North Atlantic gales for 3 months and it's still standing. We are about to order a second one after the torture test we just put the first one through. We did find it too short for our application, so added a small knee wall of wood (aka sawed off pallets). We have since order extra tubing to make it 2.5' taller (part number 4) at a very nominal cost. These will be put through the pallet kneewall to add extra support. It howls here! I'll make a youtube video of how we made the economical knee wall and increased the height. We will add a few snow load supports too and I'll put that in the video as well. The end wall wiggle wire channel instructions are not helpful, but its pretty obvious how to attached it. The rest of the instrcutions were very clear.
