It really covers our privacy area.
Color: Off White, Size: 8 Panels, Color: Off White, Size: 8 Panels
This privacy screen really works! It is the exact size that we needed (8 panel) the white color brightens the deck and compliments the trim of our house.The weight is minimal and was easily put up by two people.As for the sturdiness, the screen is made for outdoors, so I am hoping it will stand up to rain and some wind.

Best money ever spent!
Color: Brown, Size: 6 Panels
I LOVE this divider! I live in an apartment with a covered patio that faces the parking lot and desperately needed some privacy. I was hesitant about ordering this due to mixed reviews but I'm so glad I took a chance. I bought the six panel in brown and it came in perfect condition, covers the entire opening, it's lightweight but sturdy enough for wind. In the 5-6 months I've had it outside it only blew over once in a hurricane and that was my fault. I should have taken it down, I knew the storm was coming...but no damage was done! It looks amazing and now I can go out on my patio day or night with complete privacy. If you're on the fence as I was, get it! Great product!
