Great Divider, Just Needed Anchoring for Outdoor Use
Color: Grey, Size: 6 Panel
This room divider is very nice—stylish, lightweight, and easy to set up. I’m using it outdoors, which may not be its intended use, and I found that wind can knock it over pretty easily. Once I anchored it down, though, it worked just fine and looks great in the space. Indoors, I imagine it would be perfect right out of the box. Overall, a solid purchase with just one small adjustment needed for my setup.

Good Quality
Color: White, Size: 4 Panel
They are made with good quality. However I bought them to help with blocking outside light and the white does not do that.

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
