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,White

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 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!

Easy to install. Looks ok: reduces air flow. Not total draft protection but helps a lot.

Easy to install and keeps out all of the noise and drafts from the hall in my apartment building this product has been used before at another location for an even bigger Gap and work very well would recommend to anyone that has a gap under there door

This product was okay but not as solid as the double sided one.

I am very disappointed with this door draft stopper. It was advertised as an effective one-sided under-door draft blocker, but it did not perform as described. The material is thin and flimsy, providing very little insulation or draft protection. Even after cutting it to the correct size, it did not fit snugly under the door and left noticeable gaps where cold air still came through. Because it doesn’t stay firmly in place, it constantly shifts and needs readjustment. Installation was also more frustrating than expected, and the overall construction feels cheap. For a product meant to block drafts and improve energy efficiency, this fell far short of expectations. I would not recommend this draft stopper unless the design and materials are significantly improved. There are much better options available.

Easy to put on. Made well. Works great

This was amazing, it was so easy to install. I put it on a side door that goes outside and the door opens and closes just fine. it was just peel and stick. I did have to cut a little bit off cuz the door was shorter but it fits perfectly. Ordering two more for my other doors.

great item and useful

Good quality of material and did the job well

Apart from getting the wrong colour, it works fine

Works great!
