Good quality
Color: Chocolate, Size: 8 Panel
Very nice looking divider. We are using as a privacy divider around our hot tub. We have not left it out in the weather yet due to many storms coming through.

Great privacy option for townhome deck!
Color: White, Size: 6 Panel, Color: White, Size: 6 Panel
Deck privacy! I wanted a way to add some privacy to my second floor townhome deck. It’s been holding up well and doesn’t look junky! I used zip ties on one end so I can open and close it as I wish. Great solution to living in close quarters to your neighbors! I purchased the six panel and it’s a perfect size

Easy assemble and not to big!
Color: Black, Size: 132in-Large Metal Base
I bought this because I fo a lot of zoom/teams meetings and work just mandated no false backgrounds (don’t ask) soooo to hide my real home and allow others to roam free while I work I got this. Easy to assemble although you will need some space. I thought I might be to big at 11’ wide as I have a small desk area but actually it’s perfect and could use a couple more panels. Leaves just enough room so I’m not completely cocooned - I can move my chair and get up walk behind chair and exit space. Great deal and tax deductible!

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.
