Product review (5 stars): A miracle of engineering!
For years, I'd been looking at the hideously mangled and discolored flaps of our disposal in the kitchen sink, and it was a nauseating sight. I wasn't keen on taking the disposal off to replace the gasket, so I thought I'd give this collar a try. As instructed by another reviewer, I used a razor sharp knife to cut away the existing (and disgusting) flaps, which wasn't difficult. Then I just popped the collar into place! It was a perfect fit and is totally secure... but is also easy to remove and clean. It immediately reduced the noise from the disposal, too. It's true that water take a bit longer to get down the drain now, but that's not a problem for me.

A few weeks after installing the collar, I ended up replacing my sink and therefore had the opportunity to get a whole new garbage disposal gasket with flaps. But you know what? I liked the Quiet Collar so much that I just reused it with the new sink! I figure it's a lot more convenient to be able to clean the collar as need or replace it. In fact, I think I'll buy an extra one as a spare.
