Instructions are useless
Size: 1 Panel
The instructions are poorly written and not very helpful. The divider itself is easy to assemble, and honestly, it would’ve been quicker if I had skipped the directions altogether. Once put together, though, it works as intended.

This was the best
Size: 1 Panel
This divider is great for creating a little privacy or separating a small area without taking up much space. The fabric is thick enough to block visual clutter, and the frame is lightweight but stable once it’s opened. It folds flat for storage, which is convenient if you only need it occasionally. Assembly was straightforward, and it was the perfect size. It’s a practical piece for apartments, studios, or home offices where you want a quick, temporary partition.

Good privacy screen
Size: 1 Panel, Size: 1 Panel
This is a good privacy screen that's easy to assemble and looks nice. Be a little careful moving it, as the corners can twist. It's sturdy once in place, and the thick material is completely opaque. If the folds bother you, you might want to iron it, but I'm happy with it as is.

Lightweight divider that works well for video call backgrounds
Size: 1 Panel
This divider works fine for what it is, but it’s definitely on the lightweight side. Setup was very easy and only took a few minutes. The frame is fairly light, so it’s easy to move around or reposition if needed. That said, the tradeoff is that it’s not especially sturdy. It stands fine on its own but I wouldn’t expect it to handle much bumping or movement. I mainly bought it to use as a background for Zoom calls when I’m working from my den, and for that purpose it works great. The fabric panel blocks the room behind me and gives a cleaner background on camera. It’s not huge though. To keep the camera from seeing around it, I have to position it directly behind my chair. If you’re expecting it to divide a large room or create a big privacy barrier, it may feel a bit small. Overall, it does the job and works well for temporary setups or video call backgrounds, but the lightweight frame keeps it from feeling like a premium divider. The product description and photos are accurate.

Sent Wrong Pieces
Size: 1 Panel, Size: 1 Panel
I really, really wanted to like this - and, in theory, I really, really should have! The instructions were easy to follow and assembly took about five minutes. The assembled screen is lightweight and easy to move. It was a great size and exactly what I was looking for except....I wasn't sent the correct pieces. Instead of receiving 4 elbow pieces and 4 feet, I received 2 elbow pieces and 8 feet - meaning that the bottom part of the fabric just hangs there and, overall, the divider is extremely unstable because there is no horizontal support on the bottom. Thankfully, there are Velcro tabs on the side of the fabric so I can use it if I don't plan to move it even 1 cm, but otherwise, what I received is not usable for what I needed it for. Additionally, the fabric is made of polyester and catches animal hair very easily. Had I received the correct pieces, this would be a good buy for the money. Unfortunately, overall, I'm disappointed.
