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

Beautiful, sturdy, lightweight.
Color: Natual, Pattern Name: Divider, Color: Natual, Pattern Name: Divider
This screen is beautiful, lightweight and well-made. There is no splintering of the wood like I read in some reviews. The white fabric is thick and sturdy and even. The brass hinges seem to be high quality and were mounted precisely. This screen came right out of the box completely assembled. It was boxed well and there was no shipping damage.
I will enjoy using this as a backdrop when I am on Zoom and as a room divider in my studio.
I paid $75 for this and I think that is a bargain! I am very happy with this purchase.

Beautiful
Color: Natual, Pattern Name: Divider
Okay now! This is exactly what i needed. Perfect and no assembly required. Love the smell of the bamboo wood. Lightweight and very portable and great size. Ran around town all day the other day and for nothing that wasnt more expensive and just plain ugly. This is absolutely beautiful and well worth the money and it looks beautiful. What is depicted is exactly correct and that’s why there is no need to post another photo.

Nice panels to hide unsightly areas
Color: Black, Pattern Name: Divider
These are nice panels with a modern look to hide those unsightly places in your basement or utility areas and still allow ready access. Used mine in our large laundry room to block the view of the furnace and water heater in lieu of building a wall. The black and white basic pattern blended well with the walls and white appliances and improves the casual look of the room. I would not call construction overly rigid as they will not stand up to rough treatment or childrens areas well.
