I purchased 9 of these shades (different sizes ) for my newly built, screened in Sun Porch last year. I could not find shades for outdoor use. I searched the internet & all the stores. Then finally found these on Great Offer Stock.com. PERFECT! !! Every size I needed was available. (And my screens are not standard size) The bamboo is perfect for privacy when I want it, (& still allow me to see out while others can't see in) PERFECT! This 1 screen needed to be replaced this year. For some reason the bamboo broke in a couple places. The price is really very good . Especially for custom fit sized shades. I live in a cold weather state so, I took them down in the winter & put them back up this spring. And that's because they are mounted over the screens. ..there are no windows. They are open to the elements. Thank-you Great Offer Stock.com! I hope you continue to sell these awesome bamboo shades!
