This product was okay, but it would have been so much better with instructions. I'm not saying that it is difficult to use; it just would have been better with instructions. I used for my the back door. We live in an old mobile home, and we do not use the back door for various reasons. So I needed something to block off all of the drafts. I put this by the seal, but I guess because there is some large gaps with the back door I had to use some duct tape as well. It was okay if you are in a pinch (we were getting ready for snow 🥶), but I'm not sure if I would buy it again.
