Does not withstand any breeze.
Color: Grey
Not sturdy, tips over easily due to a small base and ultra light weight. Instructions were not much help but it’s pretty easy to figure out without them. Material is as expected.

Quick to arrive, quick to disappoint
Color: Black
Where do I start. Well. The only thing going for this divider was the fast shipping and affordability. But please be careful with the latter. This is exactly the type of product that teaches you that you get what you pay for. The assembly was ridiculous and lacking a lot of information and the tolerances to several of the pole pieces were incorrect. It is also very flimsy when assembled and I do not recommend buying this unless you absolutely need an urgent room divider. Best to save your money and get something sturdier.

Easy to assemble
Color: Grey, Color: Grey
Staying in a flex bedroom for few nights and got it to get some more coverage, super fast and easy to assemble, no tools or muscles needed, just pay attention to the ends of the bars : 2 vertical bottoms were marked, 4 horizontal ends are different to be easily attached to vertical frame; very lightweight but sturdy, nice shade of gray, the room still feels bright snd spacious; matches the description
