This is definitely a high quality product and I'm expecting years of use from it.

However, there are numerous "huh?" moments with the assembly instructions. Most can be figured out by reading and re-reading the steps and comparing the parts to the illustrations. I never did get the screws in the four corners of the roof in place though. The part and the screw hole are just far enough apart that no amount of effort could get the screw in. In spite of the illustrations for part BYT it's the one part that could be inserted in the right place but in a few ways. I'm sure I got it right, but those four holes remain empty.

The skylight is nice but must be a new part because the end gables lacked a necessary slot for its center rib. I had to back up a couple of steps then take a knife to add 1/4 inch slots on both ends. Then it went in very well.
