I’ve been looking for your product since we had central air installed 4 years ago. Our air conditioning contractor didn’t know of any solution to the cold drafts we were getting and I’m sure our oil costs were adversely impacted. Luckily, I did one more Google search and came up with Elima-Draft and knew instantly, your product was what I needed. They impressed me as a quality product, fulfilling my specific need, and the fast shipping was the icing on the cake. Well done!
