My backdoor does not have a screen door and I would like to leave it open during the spring and fall just for fresh air. I saw the Magic Mesh advertised on T.V., and I thought it may work perfect for what I need. I was wondering if anyone has purchased it and if it effectively works. Does it stay up strong and easy to put up? It claims to be easy to use, but I would rather get the opinions of others before investing money into one.
