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.

Great Product that does exactly what it says it will.
Color: Beige, Size: 34"- 3 Panel
I really enjoy this product and it does exactly what it describes. I use it on my balcony. It is effective, but still very lightweight. It is easy to assemble as well. The price point is excellent. Also, I had an interaction with the company about an issue and they were incredibly responsive and helpful, fixing the issue immediately. Highly recommend.

Great WFH screen for video calls
Color: Black, Size: 22"- 4 Panel
I share a workspace with my hubs since we both work from home. I have the attention span of a 🐿️ and need this so I can focus on my work and not get distracted by him, since he is very amusing to watch. This screen is very lightweight and the panels can move and create a little cubicle around your workspace. I personally loved cubicles & despise open space seating, even at home. The ADHDer in my loves being able to block things away from my field of vision. These panels also hide any mess behind you, especially if you forget to blur the background on Teams or Zoom calls or if you don’t have the option to change your backgrounds. This was fairly easy to put together and very easy to move and adjust. The screen is a much better option than a sheet as I’ve seen others use on calls.🤦🏻‍♀️😂 I’m not sure how it will stand up around rambunctious pets or kids, but fairly certain it takes quite a push to knock it over. We have four cats & I’m pretty sure someone would try to climb this, which is why they’re not allowed in our workspace.

Difficult to assemble, but a good basic divider
Color: Beige, Size: 22"- 4 Panel
I bought this to use as a background for when I have video calls. I wish I'd ordered the 6- or even 8-panel to block a little more, but that's my own error. It still covers a good portion of the room, so I'll make do, or maybe buy another at a later date to expand it. It looks ok, if a little plain. The fabric panels have creases in them from being folded and will need to be steamed or ironed out for a nicer look. It would be easy to make your own panels as well, if you're so inclined. The construction is decent. The frame is lightweight and if you don't angle the base supports the right way it may tip over if you extend it too far. The fabric panels aren't the highest quality, but are sturdy enough. They seem like they would handle being thrown in the wash well. The only issue I have with it is that it was so difficult to put together. The push latches that connect the poles don't push it well and hurt my hands. The fabric panels are sized to be extremely taut, which makes it very difficult to get them on the bars without forcing the bar to bend slightly. Overall, this is a good divider if you're looking for something simple and functional without being too worried about aesthetic. It's also a good, inexpensive base if you want to make your own custom panels.
