Great Dividers
Size: 6 Panel-120"W, Color: Beige
Love these!! Many uses. Simple, nice looking, sturdy overall. Well made. Bought to divide the unsightly storage area from the calm rest area in the basement. Also, these worked well for our garage party where the dividers let light and air in, though blocked the view of our party area from the cars driving by.

Just what I needed
Size: 4 Panel-136"W, Color: Black
I have a one bedroom apt and my son stays with me half the time. He has an air mattress in the living room until I can afford a 2 bedroom. But he’s in his early teens and needs privacy. I bought this after looking online at may of these. I’m so glad I went with this one. It covers his air mattress 3/4 of the way around and now he has his own little nook. I also gave him some led lamps and he might it like his own little nightclub. He LOVES it. And now he’s excited to be in his space. The quality is so good and there’s no see through, no gaps, it’s perfect.

Instructions could be clearer, but assembles well and is sturdy
Size: 3 Panel-102"W, Color: Black
The only reason for the lack of a star is the iffy instructions. There are a few different washers and the instructions could make the difference a LOT easier to understand and thereby reduce the need to re-do things. Other than that, the panels were easy to assemble and the parts fit well together. I was able to disassemble the screens and store them for a future use, which is nice. One caution - the feet that make the panels stand up will likely be a trip hazard, so be sure to plan the location for this device carefully.

Awesome product!!!
Size: 3 Panel-102"W, Color: Beige, Size: 3 Panel-102"W, Color: Beige
This thing is really awesome. I actually bought 2 of them and made myself a nice little enclosure to keep out any peeping Toms while I’m trying to work on my summer tan. What I was looking for is FULL privacy and this DEFINITELY provides that. Fabric is completely opaque, you cannot see anything through it which is exactly what I needed. Another huge bonus is the strips of fabric to cover the spaces in between the panels, giving TRUE privacy. This is a really well-made product, great design, great structure, and pretty easy to put together overall. The only downside is that with strong gusts of wind, it wants to tip over so as you can see I secured the bottom feet with a couple bricks to make it stable and that did the trick. But to me that is a minor inconvenience given all its other great aspects. So many other privacy dividers were still see-through… totally defeating the purpose. But this one is absolutely full privacy and PERFECT for what I needed it for!!!
