Garbage
Size: 6FT*6FT, Color: Black
This product is absolute garbage! It literally took all day to put it together and if the air conditioning blows on it the wrong way than the whole thing top over and it falls apart.
It’s not made of quality material and is very flimsy. The only reason I’m not returning it is because it’s too difficult to put together and I don’t wanna spend that much time trying to take it apart. Do not buy this!

Cheap
Size: 6FT*6FT, Color: Black
They serve their purpose as long as you leve them in one place and not moving them around and they're kinda flimsy and some of the velcros are cut too short and can't stay closed

Really adorable & functional room divider! I love mine!
Color: Dark Coffee, Size: 4 Panel
Really beautiful divider. I use it out on my patio at my apartment building to provide privacy, shade & keep my things safe. At 6 foot tall and 4 panels (I strongly suggest 4 panels) it's quite a lovely addition to my home. It's delicate so handle carefully but it comes completely put together & just set it up. Being able to move it inside or outside or wherever because it's so light makes it very mobile. It's not too opaque you can see through it but if it's for total privacy use a tablecloth or something behind it to make it less see through. It's strong and big and I had a question for their cs and they responded immediately and handled it right away which is a sign of a good company. It's light so make sure you secure it if it's windy for stability.

Nice Look
Color: Dark Coffee, Size: 8 Panel
Attractive and Very versatile. Pretty sturdy, but use care if you buy larger screens when moving. Hinges are small so moving it recklessly could break them. Overall I would recommend this screen. I love it
