Best CUISINART Coffee Grinders for Portafilter

briefly, here's how the cuisinart burr mill is supposed to work.

i still have the original food processor model made by cuisinart.

i called to late and the warranty had expired so cuisinart would do nothing for me.

the good news is that when i called cuisinart directly and gave them the serial number, they were willing to replace the unit for no charge.
