Nice once put together.
Color: Black, Size: 88"- 4 Panel
I really enjoyed these ones. They got put up, putting them together was a two-man task and not very easy at all. They work really good. They're very heavy duty. You can hang things on them. I kick mine out of the way and they work like a charm!

Not worth it!
Size: 6FT*6FT, Color: Black
These are the terrible. They keep falling down. The bottom part doesn't stay tight so it keeps turning making it in possible to stay standing. Its the absolute worst!
