Product review (1 stars): The Worst I've ever had
This device catches all kind of food particles on the underside which seem to ooze together in a nasty bad smelling slime.  When removed to clean it you find that there are all kinds of nooks and crannies that are almost impossible to get to so that they can be cleaned.  I have to scrub it with a toothbrush.  It is really a very bad design.  It also seems to trap food particles between itself and the tube/drain that attaches to the garbage disposal so that I have to run a brush around that area also to clean off the smelly goo.  Yuck.
