Product review (5 stars): Simple solution to a noisy problem
Bought a 3/4 HP Insinkerator, and the rubber baffle was very good at silencing the disposal, but waste had to be pushed thru it into the disposal, and would not drop into the disposer with water flowing, a minor pain.

This baffle has slots cut in the unit to allow "fingers" of rubber that pass waste items into the disposer with normal water flow...  It is not a quiet as the old baffle (which was nearly silent), but is quiet enough...
