Finally, My Ducks Are Sealed

Look, I'll be honest. I bought this because I have a serious duck problem. Not drafts. Ducks. They kept getting into my garage and I needed a solution. Well, I'm happy to report that after installing this weatherstrip around my door, not a single duck has breached the perimeter. Zero ducks. The foam creates a tight seal that apparently ducks find impenetrable. They just stand outside now, judging me. As a bonus, it also stops cold air from coming in, which I guess is what it's actually for. But let's be real, you're buying Duck Brand because you trust ducks to know about sealing things. It's right there in the name. Would a duck lie to you? No. Ducks are honest. Easy to install, sticks well, and comes with two rolls so you can seal twice as many ducks out of your life. Five stars, would recommend to anyone with a duck situation or, I suppose, a draft situation.

Worked as expected

Easy to install, the adhesive sticks well and assuming you purchase the correct size, it fits the gaps well, without affecting the door/windows opening/closing.

When that old winter wind comes a'whistling...

I live in an old house. I don't need to open my door to see daylight. Or that was true until I used this outstanding weatherstripping. Now, you may think that weatherstripping is weatherstripping, but Duck Brand is a roll above. Easy to use. Doesn't mash down after many uses. And most importantly will keep those howling winds where they belong - outside.
