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!

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

Pretty good, especially for this price point.

Color: Beige, Size: 21.5"- 1 Panel

This is merely a piece of cloth stretched between the frame borders, but it works perfectly. It arrived quickly, all parts present and in good condition. I didn't put the castors on, as it will be more or less always in one position. I simply attached some felt sliders on the bottom to prevent scratching the floor and to allow clearance for the center screw (which is not flush fit). Overall, a reasonable deal for the price point.
