Review on 36 Inch Fowong Door Draft Stopper: Heavy Duty, Water-Proof & Weatherproof Under Door Guard To Reduce Noise And Save Energy! by Walter Harmon

I have roommates, and old doors with huge gaps on the bottoms. I needed to do something to drown out the noise from one bedroom to another. I looked at all sorts of soundproofing stuff, but turns out, these are all I needed! Thank goodness, because they're inexpensive (I could afford to buy one for every door), easy to install, machine washable, don't look gaudy, fit the door frame well (which is hard to find for 30" wide doors), and do a great job at blocking out noise! I love that they come with the Velcro strips that make it possible to adhere the item right to the door. I'm happy with my purchase!
