Like many other reviewers on this site, I was skeptical about the Evelots Door Draft Stoppers. When they arrived, I almost did not install them because I thought they looked flimsy. But I thoroughly cleaned and dried the installation areas and stuck them right on. I put them on 3 exterior doors and a hall door. The exterior doors drag over throw rugs and they hold their shape and keep a tight seal on the floor. We have hardwood floors down the hall into our family room and the dog hair always seems to gather behind the door, so the strip I have there keeps everything in check. If you wrote a bad review about this product, and have not tried it I recommend you pull it out and give it a chance. I live in a Charlotte, NC, so I cannot say how these would handle the cold. But I do know they handled the hot summer without a problem and greatly cut down on drafts that I previously had. I would recommend these strips for ease of use and effectiveness. They many not look great out of the box, but they quickly disappear after you put them on.
