Great quality item!  The shade is durable water resistant fabric that should last a long time.   It comes with all of the hardware needed for installation.  All of the corners and hems are reinforced.   I would definitely leave the screw partially loose so that when it gets some slack, you can tighten it up.   The color is  neutral and matches my house perfectly.   
This will allow some light and water thru, but provides a lot of protection from the elements.
