Fair Quality, Hour and a half build
Color: Black, Size: 132in-Large Metal Base
Key things: It does (more or less, not completely) fold in on itself, it does block nearly all visibility (especially from an angle), it was only about an hour and thirty minutes to put together, and it is light weight. Do I recommend? Yeah.

Assembly was a bit rough
Color: Black, Size: 132in-Large Metal Base
It is serving the purpose it is bought for. However the assembly was harder than it should have been. Joining the parts A and B (two iron pipes) was very hard. We can't use any tools to do that and it has to be done manually and every joint was very tight and very hard to to do. I had to struggle to make 24 joints for the length I need. At one point I was going to return it, but I needed it very badly so continued with the assembly.
