Product review (1 stars): Water does not drain.
I believe that this is designed to trap a layer of water in the sink so that noise is kept at a minimum. The real world result of this is that water (and food waste) does not drain in a timely manner leaving you with a soupy mess to do dishes in unless you physically open the rubber drain with your hand or utensil.  I would gladly trade a little noise for a good draining sink.  How long do you run the garbage disposal for anyway?  A few minutes at most, right?
I am now buying a "regular" baffle to replace this one in the hope of getting my sink back.
