Product review (5 stars): Good value and cuts down sound dramatically
We purchased this after finding out how nasty the old one had become, having never been cleaned.  This new one works great and really cuts down the amount of sound heard from operation of the disposal.  Some reviewers complain that it drains too slowly, but I find that this might be by design, since the water sitting on top of the baffle helps to cut down the amount of sound heard.  We now like to take it out every week or two and run it through a dishwasher cycle with the dishes, just to keep it clean.

Do yourself a favor, if you haven't cleaned out your baffle before, pull it out yourself and replace it!  It pulls out very easily and fits right back in once you figure out where it seats properly.
