Good coverage and size, looks nice and easy to use.
Color: Black, Size: 6 Panel
My son uses this to partially cover his window as he is in a high rise and people can look in. It is tall enough and wide enough to provide reasonable coverage and because it doesn't require putting it together, it is very handy to use immediately. Good value for the dollar and looks nice.

Perfect for privacy!
Color: Black, Size: 3 Panel, Color: Black, Size: 3 Panel
This 3 panel room divider came in in good shape. I am pleased with how it looks. It feels a little cheap, but I was aware of that from the reviews I read. I really like the dual hinges, which is one main reason I went with this one. I also got this one for the 3 panels and the black color. I plan to use it to give the guest rooms a little privacy for when they get up to go to the restroom. I took a few pictures when I was playing around with it and attached those.
