Beautiful, rebuilt La Pavoni Zip grinder, with new bearings, recent burrs, and new doser lid.  The grounds tray, and semi worthless onboard tamper are even still present (a lot of these have been removed or lost with vintage Zips.)  
 
These heavy, low profile commercial grinders remind us of WWII Axis tank designs.  Needless to say, this won't be "breaking" on you anytime soon!  (Just don't try to invade Poland with it.  Though the current regime there certainly could use a takeover.)  
 
Doser action is smooth, and works flawlessly.
 
As we like to say, this will be the last espresso grinder you'll ever need to buy.
