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.

Beautiful brown privacy screen!
Color: Brown, Size: 3 Panel, Color: Brown, Size: 3 Panel
Why did you pick this product vs others?: The measurements were perfect for what I was looking for.  The length and width are the same as my rattan raised garden bed which I have placed in front of the screen on the deck.  This secures the screen so there is no issue of weather conditions. I have been looking for weeks for a privacy screen at every possible product and combination. and almost gave up when I noticed the measurements of the screen would fit behind my raised bed!  Now I am going to plant some flowers in it.  This is a terrific buy for me.  i am so happy! Looks great: The perfect size, color, and design match my brown deck rattan furniture. Ease of assembly: No assembly which is nice in this hot weather! Room divider: It provides much needed privacy

Attractive well made and balanced
Color: Dark Mocha, Size: 3 Panel, Color: Dark Mocha, Size: 3 Panel
It would be extravagant to purchase another 3 panel divider but had gotten it so I didn’t have to look at the hallway from where I sit in the living room. It is stable. The taller size comes with a hefty shipping fee equal to the purchase price. This blocks the hallway and is attractive. My cat can push one panel to get through the passage without tipping the screen. The walnut color is a complement so I will keep it (even though I think it is overpriced
