It works to divide a room, but it's not easy to use.
Color: Grey, Size: 6 Panel
This comes in multiple pieces and you have to build every single piece including the cloth that is between the two poles. There are plastic clips to hold the sections together, but they easily come off if you move the dividers the wrong way or try to reposition it. The only thing holding it up is rectangular shaped feet on the bottom and they are a pain when you hit it with your toes. It works if you need to divide a room, but its not pretty and there are far better options. It's cheaply made and has a habit of falling down if you are trying to use it in a straight or slightly angled line.

Nice divider
Color: Black, Size: 6 Panel
Nice divider. Set up is a bear. I am a bit concerned with stability. Overall I like it.
