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

Trouble hanging
Color: White - 2 Doors
This was easy to assemble, just the right size. The only thing was the way it was hung on wall, very hard to measure the right height.
