Utility and price
Color: Light Beige, Size: 6-Panel
Good privacy screen. Reasonably priced. Attractive. Definitely for indoor use. Direct sun will shred the fabric.

Excellent Structural Privacy Barrier / Zero Assembly Required
Color: Light Beige, Size: 6-Panel
I purchased this 6-panel partition to establish a dedicated recovery zone and create a hard visual perimeter in my room. It serves exactly the function I needed without any unnecessary complexity. ​The structural execution is excellent. It effectively blocks out light and breaks up the room geometry perfectly. Despite being lightweight enough to reposition rapidly, it remains completely stable once anchored in place. ​The best part is the zero-bloat deployment—it was ready to use immediately out of the box with absolutely no complex assembly or external hardware required. Highly recommended.

Nice!!
Color: Chocolate, Size: 6-Panel
I love this divider. There was no set up at all, simply remove it out of the box, that's it. Thank you for making this easy. The divider is of great quality and easy to store away when not in use.

No assembly required
Color: Light Beige, Size: 6-Panel
Absolutely love this! Arrived in a timely manner and it’s very versatile. Blocks the light on our porch on a hot day. Very durable and stable product. The color was as expected and there is no assembly required.

Looks ok if you don't look too close. Not likely to last long.
Color: Light Beige, Size: 6-Panel, Color: Light Beige, Size: 6-Panel
Got here fast, which was great since our company "upgraded" its video conferencing software and virtual backgrounds no longer work. But I can only describe the item as rickety and sloppily built. See photos: visible gaps in the weave that show the frame through. Chewed up screws in the hinges look like someone took them out and put them back in several times... or salvaged them from another unit. On the whole, it doesn't seem sturdy. I'll be folding it up and re-deploying it several times a week, so I'll be surprised if it will still stand up in a year. Not a good value for the price, really, except that demand on these right now has prices pushed upward. I'd be happy enough if I'd spent $39.99 rather than over a hundred.
