Input:
I purchased this because I need a burr grinder for my Pavoni espresso machine.  It does not grind fine enough for any pump or piston espresso machines.  It is fine if you are just brewing in a automatic coffee machine or french press.  But if that is what you are brewing, then why would you need a burr grinder?  I wouldn't recommend this machine.
