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!

Easy to Use, Good Seal, and Durable Foam Tape
The Frost King sponge rubber foam tape is simple to apply and sticks well. It provides a solid seal for windows and doors, helping block drafts and reduce noise. The material feels durable yet flexible, and the size is convenient for home projects. Great value for quick insulation fixes.

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

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.

Not for my purpose.
I don’t know this was used to sell a window where I had a small misting system line coming out. It didn’t stay on very well and wasn’t thick enough to sell the window for my purpose. However, perhaps for other uses it would be good.

Purchased this weather stripping for the specific reason of sealing the small openings in my IKEA Greenhouse cabinet. It squishes in the openings between the glass and doors perfectly. Had to remove one strip to readjust and it still sticky enough that it’s not falling off after being removed.
