Pergola shipped and arrived within a week of ordering. Discovered a joist missing during assembly. Called customer service and they had a replacement on it's way in two days. Assembly was fairly straightforward but I recommend taking inventory of your parts, having a drill to fine tune pilot holes, and run all the nuts down the bolts prior to assembly. The coating tends to muck the threads up, making them useless. There were extras, but not many. I also ordered some stain as there are alot of touch-ups needed from shipping and assembly. Instructions were ok but take some time to understand so you avoid having to undo steps. It went together more or less as advertised. Added lights and it looks fantastic!
