Works as intended & very nicely.
Well, I wasted my money! Do not misunderstand so soon though; the seal works great for the first half of the door, for the second half it showed me the door is crooked! The adhesive sticks nicely, if you make a mistake, it allows you to go back & fix it as long as the paper is still attached to prevent the material from stretching or tearing. Once applied, you peel the tape off very easily. Looks good, if only I bought a thicker version of the same product, it would have been perfect for my use-case scenario. At-least now I know the door I used this with is not flush with the frame. So how do I fix this problem? Well, I am not going to be taking the frame off, possibly damage it, put it back on, and repaint it; so time to buy more Frost King Self-Stick Rubber Foam Weatherseal adhesive strips! Particularly the variety that stands out further so that it could make contact with the door!

Works, but it doesn't last.
Works but the stick doesn't last. I liked it until it began coming off.

Excellent adhesion
I have used various type of weather strips annd they never stays in place and the adhesive is not strong enough to hold the weather strip in place. But this "Frost King Sponge Rubber weather strip is the best. I used this strip around my garage door and it held in place for the past three months and still going strong. All you need to do clean out the wood or whatever object you are going to install and then use the hair dryer or the heat gun to warm the object, in my case he wood before installing. This will make the adhesive to stick so good you will have a hard time peeling it off. Best qulaity for the money.

Cold and drafts - be gone!
Need this to block cold air leaks with main door and a bedroom window. Worked perfectly. Easy to apply and now my front door is not drafty and the bedroom window does not leak cold air at the base of window. Great price, shipped quick and recommend seller

Good product if Amazon actually sends the size you order.
Seems like a decent product. It would help if Amazon sent the correct size I actually ordered. Tried to get a replacement and it was going to send the wrong size again, so I cancelled the replacement. It’s really frustrating when there is no chat or call in for customer service to make sure you get the correct product. I’m losing interest in ordering from Amazon anymore.

PC case use…
I bought this for a different type of use rather than something I’d put around doors and windows to seal. I got this to line the edges of my PC case/tower on the inside. It’s an old one from a brand that doesn’t even make this specific case anymore, so what isn’t broken can still be used. However, it vibrates a lot from the fans and one hard drive I still have in use along the front panel. Cut a few small strips of this padding and put them along the front and side panels. Adhesive was like any other adhesive …. sticks and stays. Black blends in with the case and isn’t noticeable. Makes for troubleshooting so much easier when I need to listen for any ticking, coil whine, etc. rather than a constant humming vibration that starts whenever the case fans’ speeds go higher. I may use what’s left along the bottom of our back door as I can see it doing just fine for such as the foam isn’t too stiff and will fit.

I use this rubber foam strip to seal the edges on the lint trap for my GE all in one washer and dryer as recommended by another user and I’m very happy with how it works for this unconventional use. Definitely meets my needs and expectations.
