Door Draft Stopper Bottom One Sided Door Draft Blockers，37" Cutable Under Door Draft Blocker Insulator Door Sweep Weather Stripping Soundproof，Fits for Interior／Exterior Doors，1 Pack,Black

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.

I had a LOT of noise entering my apartment from the hallway outside and I didn't expect it to be completely blocked, and it wasn't, but it was reduced SIGNIFICANTLY, enough that it could no longer be heard over my microphone on Zoom meetings, so it did exactly what I needed it to do. I cannot speak to blocking the draft, but it was easy to install and adjust to the proper size and the adhesion was great, stayed put right where I placed it, even with the door opening and closing multiple times a day.

Let me be honest - this thing looks and feels pretty cheap :) But I'm still giving it 4 stars because that's exactly what I expected from the listing. You get what you pay for, and it arrived quickly. I've actually bought it twice. I use both on the bathroom doors in my rental apartment because the gaps under the doors are ridiculously big. My main goal was to block the light from getting into the bedrooms, although cutting down some noise was a nice bonus. If you install it properly, it does a really good job blocking light and drafts. Mine have stayed in place without any issues. They're also super easy to trim to the right size with a pair of scissors. A couple of things to keep in mind: they're very white, so they may not match your doors, and they're super lightweight, so I wouldn't expect miracles when it comes to soundproofing. Well, I wish I didn't need these in the first place, but since big door gaps seem to be so common in apartments, I think this is a pretty good solution, just not the prettiest :)

This is a pretty good draft stopper. I bought this for a friend and it doesn't seem quite as much quality as the one I have. The one I have is more fabric than plastic. This will probably tear eventually but for now it fits her door and gives good coverage.

This is a cheap way to stop drafts from coming under your doors. Setup is so easy and takes less then 5 minutes. They are kind of flimsy and not that big in diameter, but they're convenient and they work! The sticky side of the tape holds very well to the wall, just make sure to clean the door first so it sticks better. And leave a little extra on the end if your doors are really drafty, especially on the doorknob side of the door. I made the mistake of cutting the first one to fit my door exact, I should have left about 1 inch extra on the end where the door shuts. Other then that, they are worth the price!

These work so much better than I expected! I didn't need them for the bottom of my doors, I needed them for the door jamb where it closes. I cut a little notch around where the doorknob piece catches, and when I say it cut down my draft by about 90%, I mean what I say! I put this on my side door and my front door. With this terrible ice storm we've had this winter, I realized how much heat I was losing as my money was going out the doors literally! I used one of the see-through thermal insulated curtains going into my dining room and on the other side is that first door you see. When I was going through the curtain from the kitchen, it felt like I was going outside now there was a huge difference. I highly recommend this product!

Does a great job stopping draft at the bottom of the door, easy to install. Doesn't cancel too much noise but it helps slightly. Very flexible with good adhesion.!

This is a great purchase. Not only has it stopped the draft under the door but where I live we have lots of dust storms. It cut the dust blowing under the door tremendously. Barely had to trim any off of it, just peel and stick. Hardly noticeable. It just does it thing and it works

great item and useful

Apart from getting the wrong colour, it works fine

Stops draughts under the door

Cero funciona, el material es muy ligero y se levanta fácilmente por lo que cualquier animal podría pasar sin problema.

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!
