Nice room divider!
Color: White, Size: 8 Panel
The white panels are a nice off-white color. shipped in perfect condition. Already assembled so set up was quick. We use them to separate a photo studio from the main entry. Easily covers a 6 Ft. opening to the room. They are a woven material with wood colored sticks to support the weave. They are about 6 Ft. tall at the top of the curved section but less at the hinged sections. Light and easy to set up and take down. We are straddling two different floors so the extended legs at the bottom make this easy. Not sure how to clean them but they look great so far!

Instant Privacy
Color: Beige, Size: 8 Panel
Bought this to separate a ground level living area used as an office. Works well to cover visual clutter; allows a clean look when entering the front door. Comes fully assembled. Hinges are sturdy enough, as long as the panels aren’t stretched too far; have to allow some bend between them. For the price point, quality and functionality are satisfactory.

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.
