Review: Perfect for DIY projects and general seal use. Technical review - These strips are fantastic for DIY purposes, and an awesome drop-in for most standard interior/exterior doors for weather and sound. The buckling design means they require little force to compress, and i recommend targeting 1/16th ~1mm of compression. the uncompressed height is usually around 1/4", and it can compress to about 1/8". they are about 3/8" wide. Some points will be kinked from being shipped on a roll, but they all come back flawlessly. The biggest pro is the adhesive quality. it's the high quality clear stuff, it will gladly stick to paint, raw wood, steel, glass, and more, with enough holding power to never come off. but it won't leave marks when you do remove it. If making your own custom panels that sit flush, you can route a 3/16 deep by 3/8 wide notch to get the perfect fit. If weather resistance, adhesive quality, and consistency are your goals, these are the best price to performance compared to most! Will update with photos upon project completion!
Review: Weather Strip Works! - This is a great product and plenty of it! Use the provided wipes first and the adhesive will stick! Sealed perfectly around my door.

### ⭐⭐⭐⭐ Too Thin for Our Door Frame
*by M***X on August 22, 2025*

Good product that is extremely easy to apply. The only issue is that it's too thin, leaving a noticeable gap and "draft" in the back door frame.
