Details: Starbicks barista Athena espresso works good. Buttons all work. Not sure on exact procedures on one & 2 cup operation, Very hot water comes out,but I don't know how much comes automatically, cause you can hold button for more. Makes small cups. You will need a manual. Have portafilter, large & small baskets,a thick rubber part(tamper), and a tool with phillps head on it, to remove screen for cleaning. No other pieces included.
