Love it it was perfect for what I needed it for. Good quality!
Size: 4 Panel, Color: Black
It like a very dark chocolate brown/black. What I liked most about it is that you just pull it out of the box take the long plastic film off of it and it's ready to go. It has protective feet on the bottom. It's very attractive and it was so easy. It's so nice when you have a product you don't have to assemble.

Shipped quickly and as described
It was what I expected as functionality, lightweight and easy to move about. I plan to use it in my enclosed patio to obscure weight bench and wts. My only complaint is that the bamboo cover on one edge is not secure. But I will probably use a magic marker to cover the natural back that is showing. I don’t have time to return it as my event is coming soon.

Good product, needs double hinges for versatility.
Size: 6 Panel, Color: Brown
Blocks out all the light, looks good, good color. Only con is that it is not double hinged so it is hard to position the extra panels because I bout 6 panels instead of the 4 I usually get. Good deal, very decent price with the free delivery. Very clean packaging, came in great shape, no smell or odor from the factory.

Very Pleased with Room Divider
Size: 4 Panel, Color: Brown
This room divider is even better than I expected. It's sturdy but is lightweight enough that I could get the box up a flight of stairs with no problem whatsoever. It folds and unfolds easily and is very easy to move. And there's no assembly required! It really is woven and is quite attractive. The main reason I chose this item was price (although I did like the way it looked) and I got more for my money than I thought I would.
