Economical, easy to use, and effective.
It's a great product if you're allergic to the foam earplugs. Soak them in mild, soapy water after each use and they're ready to go for the next night. They're soft and reshapable, a little like Play doh, but smoother and denser. You can adust them, make them larger or smaller by combining and separating the compound.<br /><br />And they're more comfortable but a little less effective at blocking noise than the foam. I can't really say how often you should reuse them, and I wish there were some information about that.<br /><br />A good answer at noise-induced insomnia.
