Review on Awoco Speeds Commercial Indoor Curtain by Petr Webster

I live in North Texas and in the summer I have problems with flies, bugs and cold air escaping when I open the back door to use the patio. I installed this air curtain a week or two ago and it helps a lot. The number of flies and other flying insects entering my home has been drastically reduced by the release of cold air. It makes a little noise but it's worth it. Also, I bought it "lightly used" for $200 instead of $280, and because it came in the original box everything was still wrapped in plastic. I suspect it could just be a return that was never opened. My wife and I use our patio and backyard every day, and I feel like it helps me win the war on bugs, flies, and cold air leakage. I'm sure it will be the same in winter when it helps keep the cold air out.
