Excellent privacy shade.
Color: Coal Black
This delivered on exactly what it promises. So happy with the quality for the value. The shades are a fabric, nylon like, that are attached with a pocket on one end and velcro that adheres around the bar on the other.
This was incredibly easy and straightforward to put together. Every piece was clearly labeled, coordinated with the instruction sheet, and fit perfectly. Honestly, I wasn’t planning to leave a review but I was so impressed by how clearly labeled and well explained the instructions were that I felt compelled to note it. Especially for anyone who doesn’t like putting things together, or is used to subpar instructions, this is leagues above the rest. It’s such a simple build anyway, but after buying so many things that barely fit as they should, this stands out.
It is lightweight and easy to move. Offers privacy when opened, then can be folded out of the way. It looks exactly as pictured. No complaints, it’s a solid item and worth the price.

Decent quality for the price
Color: Grey
Decent quality for the price. Other privacy screens were extremely out of my budget, but this looks and works just fine- I just needed something simple to place behind my couch to hide some clutter. It took me about a half hour to assemble, but it was easy enough.
It might be due to my carpeting, but I don't trust that the screen would be stable enough to stand freely without falling. Thankfully my
plan all along was to wedge the screen between the couch and a box of clutter anyway, so for me it works as l'd planned!

Overpriced but effective.
Color: Cream
I happened to get lucky and get a warehouse deal at an additional 30% discount. Even at $25, it feels a little overpriced. But it was easy to assemble and serves its purpose. If you line the Velcro up exactly, the panels sag, if you stretch past even, but where it still grips, they look pretty ok. It is very light and does fold very compact for easy storage.

Great price for a great product
Color: Coal Black
Excellent quality and great price to boot. Easy to assemble and folds up easily to be stored. We are using it as a privacy screen when we have company that needs to sleep on the couch and also to block off a hallway leading to a guest suite. It looks great and is as described in the ad
