Product review (5 stars): The picture isn't correct, but it works.
It works. The picture of the product isn't what I received. I was interested in the vent slot at the top of the product image. Mine has no slot but does seem to work much better than the one that came with the disposal. It was flat and would not let the water drain into the disposal because of an airlock. This design lets water run down the bottom while air can vent at the top keeping the sink from filling up.
