I Like it...Perfect sunscreen to keep the Sun off me: I Need To Test Outside Durability
Color: Natural, Size: 4 Panel, Color: Natural, Size: 4 Panel
I have Southern exposure on my 6th story balcony. For most of the year, the Sun out there is unbearable. I have had another room divider/sunscreen I have outside in all weather conditions for 9 years...and it has held up well and still going (but showing age). Hoping this one will be as durable. I will update my review after some weather conditions have put it through its paces. The divider is quite attractive and lightweight. It is perfect for what I need it for at this time, and is stable in the wind with the anchoring system I have used.

A wonderful partition to block off the room with gifts
Color: Dark Coffee, Size: 8 Panel, Color: Dark Coffee, Size: 8 Panel
If I could give these 10 stars I would. They are going to be perfect when I use them to close off one of the rooms to hide all of my granddaughter’s birthday presents. They even match my floors.
