Perfect for privacy!
Color: Black, Size: 3 Panel, Color: Black, Size: 3 Panel
This 3 panel room divider came in in good shape. I am pleased with how it looks. It feels a little cheap, but I was aware of that from the reviews I read. I really like the dual hinges, which is one main reason I went with this one. I also got this one for the 3 panels and the black color. I plan to use it to give the guest rooms a little privacy for when they get up to go to the restroom. I took a few pictures when I was playing around with it and attached those.

Pretty good.
Color: Natural Wood, Size: 6 Panel
Wrong color. Uniform color instead of 2 toned as depicted in the picture. But well made.

Exactly what I was looking for.
Color: Brown, Size: 3 Panel, Color: Brown, Size: 3 Panel
Although other reviews found this item was too lightweight and flimsy, frankly it was exactly what I was looking for. I needed to partition my workspace off from the rest of the room and I wanted something that I could easily attach to the back of an unfinished bookcase as part of creating a private space. It was perfect. Lightweight easy to handle and I didn't mind putting some nails through it. Great price point for what I needed.

Made cheaply.
Color: White, Size: 3 Panel
Seems fairly sturdy ( 3 panel white) but made with extremely cheap materials that will not last. The cheap materials are very noticeable with the white screen. No assembly needed. Would not but again.
