Easy peasy
Size: 1 Panel, Color: Black
Bought this single-panel room divider for my son so he has a little privacy when he has to keep his camera on for online classes.
It’s lightweight, easy to set up, and does the job—he can focus without me photobombing in the background. He can feel like he has his own tiny corner office, even if it’s just the basement.

It serves it's purpose!!
Size: 1 Panel, Color: Black
Product really works well & serves it's purpose! Great height & width. It's flimsy, but it will stand still when put in place.

Zero stars
Size: 1 Panel, Color: Black
The bars are impossible to screw in all the way so it’s not sturdy at all, trash and waste of time

Great product, sturdy and well made. Easy assembly.
Size: 3 Panel, Color: Beige
These are awesome! They were easy to assemble. They are lightweight and easy to move. I was able to easily put all 6 pieces -(I ordered two sets)-into the back of my SUV at once, by myself (and I'm a short, older lady). Quality material. Very sturdy and steady. The first set I opened was a used one and did not include instructions, but it was still very easy to assemble and figure out. I recommend using a battery powered screwdriver. With that, the assembly of all 6 panels took less than 45 minutes.

Defective product
Size: 1 Panel, Color: Black
All screws cannot fit with each connectors. The Allen key provided is useless because it doesn’t fit into screws.
