I had two small closets by our front door that had a pretty good draft coming from the gap at the bottom of the door. I was able to cut the one sleeve they provide in half and do both doors. It was significantly better that I expected. Barely any noticeable draft coming through now. I mounted the blockers on the inside of the door so they are not visible from the outside. Means I don't need to remove after the winter. Installed on the inside they also seal against the door jam to add to the air tightness. I few helpful hints: If you use a steam iron you can smooth out any creases in the sleeve to give it a cleaner look (sleeve was folded several times in the packaging). Measure the sleeve carefully before cutting. They can't be corrected if cut it too short but you could use a small piece of any extra foam between the (3) sections they supply so the foam cut is not as critical. If cutting the foam, I suggest inserting the cut side into the sleeve first so the exposed part is the "seal" end. It will probably hold up better this way. The products comes with no instructions (one of the reasons I am writing this review). Refer to the product listing on Amazon as they do supply some information on installation that's not obvious (e.g., heat the adhesive before attaching to the door). Given the product price point and effectiveness, I think this is a great buy. PS: I noted several people are using this on the side of the door to seal gaps. More power to them if it works for them but I would suggest looking to see if the door is properly aligned so that the door is actually seated against the jam trim. I found that works wonders for reducing drafts from the vertical part of the door. There's plenty on videos for doing that on the web if needed.

This draft stopper works perfectly on my apartment door. It does exactly what it’s advertised to do—it keeps my apartment completely free of cold drafts, and it’s been amazing at blocking out the unwanted smells coming from the building's hallways. It was easy to set up and fits great. Highly recommend this to anyone living in an apartment building who wants a bit more insulation and privacy!
