Very nice quality and appearance
Color: Beige
They were surprisingly stout and went together well. We had to return them because when we took them to where they would be used, they were too big to work in that location. Dang. But if we needed them in the future, I wouldn't hesitate to purchase them.

Good Multi-use Panels
Color: Grey
These panels were easy to assemble and stand sturdy. i will use them to block the sun when I am outside doing yard work in the heat. I'm sure I will find other uses for them too.

We threw it away
Color: Grey
This thing cannot stand on its own, the side bars bend since it is not sturdy enough to handle the material screens. After assembly, I was so mad at it, the pleasure of crushing it was better than returning it. I tryed to think of other ways to use it, but could not… i kept the screens, they are the strongest part of this thing. Very disappointing

Works well
Color: Beige
Does the trick for privacy and some noise blockage. This takes two people to put together. The construction make it easy to assemble, but makes it just as easy to come apart on its own.
