I got these dividers for outdoor use for some privacy from neighbors. They arrived quickly and were easy to set up. They look good, and though the legs don’t offer stability against any amount of wind—which I expected as it wasn’t advertised for outdoor use—all it took was placing a cinder block on the feet to hold it up right. Coverage is good, it’s easy to fold and move as needed, and it’s light weight. All in all a decent product. I will caution the purchase of “used like-new,” as both of the dividers I ordered were previously returned items, and one came missing a cap, instructions were not included, and the poles were all mixed up and not properly labeled. If I had not ordered a second divider (which did include the instructions) I would have had a much harder time figuring out which pieces were which and how to put them together.

So versatile! Perfect solution for dividing a room.

Perfect solution for my space. My office has to double as the hangout room for the kids and I wanted something that would block off my computer so it is left alone. This space allows me to close off my computer as much or as little as I want. It is lightweight yet has sturdy feet. This is important so that if it gets bumped it won’t topple over. The price was great and the build time wasn’t too bad! I would recommend two people for set up. I went with the grey panels and I think I’ll end up hanging some twinkle lights at some point. Great purchase!

4/5 Stars

Size: 4 Panel-88'', Color: Black

Very tall and easy to set up, the only thing I will say is that they do have large gaps in between, so you won't have 100% privacy unless you add a curtain in the back. Other than that, they are easy to fold, sturdy, and esy to assemble. The gaps are an easy fix so I would say they are worth it.

Great product and worth the money.

Size: 4 Panel-88'', Color: Black

Portable and stable. Perfect size and gives me the privacy I need when working from home. Stability is great as long as you place the stands correctly it won't wobble. I love it.
