Product review (4 stars): Very functional, but not a quiet design
I bought this to replace the quiet collar that came with my InSinkErator.  We had issues of food waste not really passing through the quiet collar without forcing it through.  Several reviews recommend this collar as a good replacement for that problem, "AND it is just as quiet".  Well, it is NOT anything close to as quiet as the original collar.  I will continue to use this collar as it is more convenient and a better design, but I will continue to think twice about running the disposal when the kids are sleeping.  This was never a problem before.
