In the past I have bought cheap plastic or bamboo shades at the local discount store and had to replace them every summer, sometimes twice if the bamboo molds from the moisture, or the plastic slats break from storm damage. I've only had these shades installed for 7-10 days and so far have been happy with them. Easy to install, came with all the parts and reasonably clear directions. Not heavy fabric, so you can see thru them if privacy is an issue for you, but they do let air onto the porch and do block the sun. The temperature inside the house has definitely been cooler since installing. Not the best quality, but should do the job adequately and hopefully will last a couple of summers here in the Northeast.
