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.

Easy to Apply and Install on Doors
These are very effective for reducing draft under doors - especially the front or back door of a house. I recommend laying them flat a couple of days so that when you attach to them to the door, they stay level and flat and seal draft from underneath the door. Overall, very noticeable improvement.

Sticks well and works well
Good quality weatherstrip. Sticks well and works well a little high priced.

Easy to use - read the instructions firs - great product
Don’t be like me- read the instructions first. There’s an included primer wipe that you use after wiping off the door to help the adhesive. It includes two so I figured it out on the second one but / both turned out great. I was storm prepping to keep the draft out and they work great. Just adjust to the height you want -measure length and stick. Again wipe the door first (remarkably dirtier than you probably realize) then use the primer wipe after.

Great Product!
Easy to install. Great quality. Flexible enough that opening and closing the door isn't a problem, but thick enough to keep out the cold.

Very excellent product
Amazing product for light and noise, I only put on one side of door for aesthetic purposes and it still works amazing seems like a perfect seal almost and looks natural. Only slight concern is that it makes the door close a bit slower but not really much of a con to me.

Works pretty well so far
The adhesive is good, but it tends to pull up on the ends initially. I had to stand there holding it for much longer than I expected, even with the little adhesive helper pads it comes with. It does work really well, though; it blocked the space we had under the door and has helped reduce the airflow. They look great and are light enough not to affect how the door opens.

Neat and clean, who could ask for more?
I used to have a draft stopper and I would have to lean over every day and move it. I don’t want to sound lazy but seriously? I’m done with that! This product is so nice and easy! I mean, you don’t even have to use nails it just sticks on! I would just recommend taking your time to properly place it so that you do not have to remove it and place it back on multiple times. The look is nice and clean, not some silly sloppy looking. Draft stopper that has to be moved all the time, this is really terrific

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
