Commercial Special 5/10 ft Bamboo Roll Up Blind Wooden Chicks One Side Cloth Sun Rain Storm Dust Protect Window Curtains (Brown)

A better guide or instructions on installing would be helpful.the one provided has a picture that looks nothing like the product sent. For a lay person not so practical. The bamboo slats catch fungus immediately when exposed to moisture or rain water,I just left the same open to dry out when the sun was out, which takes some time,so its a rough use product, but the black mildew dosent really go, which I don't think should happen to a treated product. Serves the purpose of blocking sunlight and even as a good block for 50-75% of heavy rainfall. Good ventilation, allowing for some air to pass through the material. Rolling up is not very precise,a few modifications by the manufacturer would make it more easy to operate.
