Just installed 5 of these in my house and I was surprised at how well they work. I worked as a carpenter years back and have installed the traditional screwed in door sweeps with the metal base and rubber sweep so I didn't expect much from these but honestly for the price I would recommend them. They're also incredibly easy to install so no carpentry skill is necessary to install. Just something to mark the length you want it and then scissors to cut the rubber. Then slap it on using the attached 3m tape while running your finger and making sure there are no gaps at the bottom.

I should say these are for INTERIOR doors. I don't think they would last or stay on exterior doors well at all.

I installed another brand of this same product on the door to my laundry room. It's a significant reduction in noise transmission.

Probably means the interior side of an exterior door.
I'd also use it for doors for rooms that aren't heated. Garage door, maybe storage rooms, large unheated closets.

My math skills are just fine. Even if you believe those SD charts, it shows they were over $4 not $3, so $6 ain't 50% less..

What would be the benefit of using them on anything but an exterior door?
I'm going to use it on my interior basement door, maybe also good for a door to an attached garage.

I have a similar one on one of my doors and it works great. You would be shocked how much sound comes through like a half inch gap at the bottom of a door.

No, but $6 is 50% more than $4. Which is what the OP said.

I tried all your suggestions, & this is what I get:
  • $8.52
  • Shipping & handling:
    $9.99 FREE
  • Promotion Applied:
    -$0.43
  • Estimated tax to be collected:
    $0.68
  • Order total:
    $8.77
  • It said I qualify for the promo, yet {for some reason}, it gives me 5% off.
