We were getting small and what seemed like not so small insects inside the house at night with standard screens. I bought a short roll of solar small insect screen at my local hardware store to see if it made a difference. It did, but too expensive as they only had short rolls. I found Metro online and I wasn't sure if I was ordering the right product, since it was online. Hard to know if you can't see it in person. It's perfect! And the price per window, especially with these longer rolls is great. Installing is easier than I expected. No more tiny insect invasion at night! What's not to like?
