Product review (1 stars): this is the worst at draining water AND being able to easily push ...
As others have stated, this is the worst at draining water AND being able to easily push waste through it.  I did not purchase at amazon as I am rating the one that came with my new evolution unit.  In addition to the above problems, I found that the rubber became distorted quickly around the perimeter (against the stainless steel opening.  I will try the alternative as others have suggested.  The only thing it does well is muffle the sound better, but I'll take the extra noise if it does a better job at everything else.
