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.

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.

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

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.

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.
