Product review (5 stars): InSinkErator QCB-AM Baffle
Wow!  What a time and energy saver this find was.  Rather than having to disassemble a kitchen sink garbage disposal to replace the worn out stock baffle,  I simply took a razor knife to cut out the old baffle, and pushed the new unit down into the sink drain.  Fit perfectly and works like a charm.  Made my day!  Wish I had the patent on this one.
