Wobbly
Color: Grey
Wobbly and the metal bars keep coming off. Be aware. I’ve tripped over them. Be careful.

Good for a quick backdrop
This works well for what I needed – a simple background for my kids’ online school. It’s lightweight and very easy to put together, and it stands up fine without needing to mount anything.
The color is listed as black, but it’s more of a dark gray in person. Not a huge deal, just something to be aware of. It’s not super heavy duty, but it does the job for privacy and as a video backdrop.
Overall, a good, portable divider that’s quick to set up and works well for light use.
