Decent value for the money.
Size: 6FT*6FT, Color: Grey
Was easy to assemble. Instructions were clear. Tools were supplied. It really needs to be assembled wherever you're going to be putting it as it can come apart easily when moved. The cross bars simply fit into open ended plastic 90 degree female ends. Overall for the money and to just have some division in a room it's a good value.

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!

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
