Held up for a year so far
Has made a major difference in climate control in our living room this year, I live in a rental, and I am not about to spend the money or or play around with their insulation. This was an easy solution, just cut it to size, peeled off the backing and attached it along the bottom of the door, realized I can't measure and cut out a little piece to finish the seal. Despite being in two pieces because of user error, it has worked great for just over a year so far. Not the most attractive addition, but that is also probably user error. I'm sure it helped in the summer, but I really noticed the difference during the winter storms.

Quality adhesive and material
Not only helps stop the draft from under the door but it has kept mice from going back and forth

Does the job.
Easy to use. I used this in my mom's apartment. There is a very large gap between the door and the floor and this closed it in well.

I love this I got the bigger package and it was enough to cover two doors it made the door look like the extension came with it to block the wind

Perfect for metal doors!
I used this to go on my storage room door in my classroom. There was constantly debris coming in from outside when the lawn company blew leaves and I feared critters were coming in, as well. This was the perfect fix! It was easy to install but take note, you need a hair dryer to heat up the glue. Not a big deal, but I didn't know ahead of time. It went on easily and has kept things from coming in. It went on a metal door and the glue hasn't released at all.

keeps everything u want/need out
I recently tried the KNEELISA 39" Black Under Door Draft Stopper, and it’s been a great little upgrade for my home. It was super easy to install just peel and stick and it fit perfectly under my door. It blocks out drafts, dust, and even some noise, which has made my room feel warmer and quieter. I also noticed fewer bugs sneaking in, which is a bonus. It’s not 100% soundproof, but for the price and ease of use, it does a solid job. Definitely worth it if you want a quick fix for door gaps.

Almost perfect
I bought the white strip to match a white door in my bedroom. There was a space about an inch below the door that let in quite a bit of light. For years, I would use a folded up towel to block the light. I was sick of doing that. So I got this strip and it was unbelievably easy to use! I did not clean the door because I didn’t want to strip any paint off the door. I simply cut it to size, pulled the lining off the sticky stuff on the strip itself, and placed it on the door. It held just fine, but I decided to go over it with 2 inch wide white duct tape that I already had. So I cut the duct tape to size and placed it at the edge of the strip just before it blocks out the light to hold it to the part where it was sticking to the door. And then, of course, it extended above that holding fast to the door itself. The duct tape was not sticking to the strip part and so I got some gorilla glue and laid thin bead and it stuck just fine! The reason I’m giving it four stars instead of five, is that the white still lets in some light but not enough to bother me, but not as completely blocked as I would’ve liked.

Completely different in quality, color, and adhesive. The product shown in the images looks premium with strong adhesive tape, but what I received is nothing like it. The strip is reddish-brown instead of black, and the adhesive is in terrible shape. The overall quality is very poor. On top of that, the entire strip was dusty, with dust even stuck to the adhesive side. I'd rate it 1/10. This feels like a scam — showing a premium-looking product and delivering a cheap, substandard version instead.
