Cheap but effective draft stopper
For the price, this does the trick to cut down on drafts coming from indoor/outdoor entryways. I applied this to both my front and back doors in my house where there’s always been a noticeable draft and it’s definitely helped to cut down on it! I do like that it’s white and blends in with the doors so it’s not super noticeable. Easy to install and stick on too just make sure to measure and cut it and good to go! This one order of the 2-pack was enough for me to do these two doors but if I decide to do my door to the garage next then I’ll need to order some more.

This product does the job to reduce drafts
Great product, good quality, and very easy to install for this "Senior Lady". Had adhesive backing and also comes with an adhesive prep pad to wipe on the door where you will apply it. Instructions are easy to follow. It really stays put too! Sure did the job stopping drafts from under my door. Looks great too. My pictures show the installation process with my flashlight shining on the bottom of the door - notice the big gap along the bottom of the door.

Overall very good and effective but sometimes doesn’t stick as efficiently as would like.

Great price, wished it didn’t fold under the door for me.
Great customer service , reached out twice to me . Easy to apply, can remove and reapply . Looks great, but mine folds over the door some parts which shouldn’t, but I have already placed it higher. Any higher, there will be a gap. Maybe my floor is uneven. I use it on non carpet area and I have a mat by the door which keeps getting stuck by this thing, so maybe a having a mat there is no longer ideal.

Easy and effective
This is my first winter having it in place and there is a very clear difference in the temperature on the bottom floor of my town home as opposed to last year - finally the heat is staying in! The product was very easy to apply (I am a bumbler when it comes to home repair and I had zero difficulty) and looks much better affixed to my front door than the previous gap that had caused me so much issue. If you’re searching for something to help cover that door gap, this is perfect.

They are okay, but there are better if you pay more money.
I recently had purchased a different brand where you only get 1 unit for more (about $1 more) than this pack of 2 units from GroTheory but now realize that you get what you pay for. The GroTheory ones are okay but not as good quality as the other more expensive one I bought last time. The GroTheory ones are curled up very tight and don't uncurl all that great, leaving permanent wrinkles and bends particularly on the end that was on the inside. These GroTheory ones are more plasticy whereas the other brand was more rubbery so didn't get permanent wrinkles and bends in it. That all said, these GroTheory ones are not terrible, they're certainly serviceable, but if you do really need higher quality, you'll have to look elsewhere and pay about double.

Draft Stopper
This door draft stopper saved me this winter. It was easy to apply just follow the instructions. There was enough product to fit my door, there is no cool air coming from the bottom of the door. I am able to close my door securly. It is white like the door so no one knows that it is even there. It works well and it looks good too.

Coming into the winter season, I get a draft from the hallway in my condo building, especially living on the main floor, and it's like AC coming I to my unit. As a renter, I bought this based on the reviews saying it was easy to install and to remove with the adhesive. I only prepped the door with the alcohol wipe, letting it dry before adhering the strip to the door. I don't want it to ruin the paint by making the adhesive too strong when it comes time to remove it. For removal though I would use a hair dryer to help make it sticky. For this being a two pack, awesome deal and fixed my problem with the draft! It's helped reduce some of the hallway noise as well. highly recommend
