Decent for the price. Instructions suck but most people should be able to figure it out. More below.
Color: Black, Size: 6 Panel, Color: Black, Size: 6 Panel
SUMMARY:
3 stars from me because it's firmly average. It's fine for the price. Assembly and materials are alright but I can see some caveats depending on your circumstances. Assembly instructions do a subpar job of pointing out some details.
ASSEMBLY INSTRUCTIONS:
Maybe it's because I'm autistic and/or building model kits and assembling stuff is my jam, but I honestly thought people were exaggerating when they were complaining about the instructions and I'd be able to flex my ~superior assembly skills.~ I was wrong! These instructions genuinely suck, and whoever is responsible for making them should be ashamed.
The instructions do a poor job of calling out some details regarding orientation of parts, and some of the images do not actually match the physical parts.
For example, it does not really outline the assembly of the end panels clearly, and I can see someone accidentally using the wrong poles. I've drawn over a photo to show what you should do to try and make it clearer. Additionally, the manual shows a flathead screw for bolting the feet into position, but the actual screw is not a flathead. It also does not point out the counterbore, so if you aren't paying attention you may put the foot pads onto the wrong side of the foot. It's also missing the fact that you need to use another one of the plastic pieces when you finish assembling a panel.
ACTUAL ASSEMBLY & MATERIALS:
To their credit, all of my bags were clearly labeled. The assembly process wasn't difficult. It's mostly just tedious and requires a fair amount of space. I was able to assemble it by myself without any real difficulty. However, the way it's assembled means two things.
One, the fabric parts aren't removable without disassembly. So if you want to use this in an environment where they would require cleaning, I would seriously recommend looking for another option. Or, you could buy this just to use the frame pieces and then somehow buy or make your own fabric pieces designed to be removable with velcro or something.
Two, because of the materials I really don't have a lot of faith in this thing surviving disassembly and reassembly. Like a lot of sorta-cheap-but-convenient furniture, it uses those spring-button connections and plastic inserts with self-tapping screws. Those things are not really meant to be disassembled and rethreaded. It also relies a lot on the tension of the poles and the fabric to keep everything rigid and squared, which I think puts a lot of pressure on the aforementioned buttons, plastic inserts, and the hollow metal rods. So I feel like that will also cause issues with disassembly and reassembly.
Basically once this thing is assembled, it's not really meant to be disassembled. The best you can do is spot-clean the fabric if you need to.
Speaking of the fabric, I didn't see any labels on them or anything in the manual that says what they are, but they feel like some kind of polyester. They generate static electricity pretty easily, and pet hair and debris sticks easily. So that's another downside of them not being easily removable.
For the most part it does seem pretty stable. The poles seem to be pretty uniform in length so they're all making contact with my floor. Obviously this isn't structural so it shouldn't be supporting anything, but the two main feet seem to be doing fine with keeping this thing upright.
CLOSING THOUGHTS:
Really, it's fine for what it is, but it could be better in a lot of little ways and the substandard quality of the instructions just seems unprofessional to me, which is why I'm being so harsh with my rating. Depending on your needs and environment you may want to consider a different option. Preferably one that is made to be disassembled with better materials, and/or one with fabric pieces made to be removed easily.

Not as it seems
Color: Black, Size: 6 Panel
these are awful... Each individual panel is fine, but when you put it together it can barely stand up, and the clips that hold it together keep popping off. Steer clear of this item.

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!
