Seals well
Very useful around lots of areas besides doors and windows. Works well around cracks or floor edges (trim) to seal drafts and toilet area!

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!

Nice and flexible product
This was just perfect exactly what I needed. It’s thin enough and flexible enough to fill in the gaps. And the getting a really nice pair of scissors to go with it was a welcome surprise! Highly recommend this product.

Not as good as I thought
I really wanted this 50 Feet D-Shape Rubber Weather Stripping to work, but it was a complete letdown. The material feels cheap and flimsy, and it barely sticks to anything. Even after thoroughly cleaning the surface, the adhesive started peeling off within a day. In some spots, it never adhered at all. The “50 feet” claim also feels misleading — the roll was unevenly wound, and I’m convinced there was less usable length than advertised. Cutting it was easy, but that’s about the only positive. The seal itself doesn’t hold tight, so it does little to block drafts or noise, which defeats the entire purpose. After all the effort of installing it, I ended up ripping it off and replacing it with a different brand that actually works. Save yourself the frustration — I would not recommend this product to anyone.

Good Product
Much better seal than I expected. I'm pleased with the product. Works well for what I needed to keep water out of a feed bin for animals.
