Query: Quick and easy to install, works great

I originally saw this in SkyMall magazine while on a flight. My screen door was in bad shape; it was hanging to the point where there was a large gap that bugs could fly in. I did not want to take the time, effort, or money to replace it. When I saw this Bug Off Instant Screen in skymall, I became interested. I got home and found it was on Amazon, score! I installed the product in minutes, if that. It works fantastic. The only complaint I have is at 6'4" tall, I have to duck to get through the pivot point at the top.
