What customers say about "Key Specs"
Mahlkonig K30
  • Great machine that grinds coffee consistently and easy to care for.
  • I grind my coffee for a French press, but the Capresso can be set for any type of grind you'd like.
  • So this little grinder is exactly what I wanted. It's compact, has a nice capacity hopper, and can do espresso grinds.
  • Disappointed. Settings for coarse grind are too fine for my liking.
  • Even on the coarsest setting the coffee grinds pretty darn fine.
Rancilio ROCKY HSD-ROC-SS Espresso Coffee Grinder with Doser Chamber
  • It is very adjustable and quite consistent in the grind which helps in making excellent espresso and cappuccino.
  • The Rocky does a great job with the grinding and with the doser.
  • Grinds beautiful! Quiet, looks good.
  • Perfect grind. Very adjustable and easy to use.
  • You have to grind a lot of beans in order to get the doser to work consistently.

What customers say about "Features"
Mahlkonig K30
  • It is durable, and I have never had any mechanical problems with it.
  • Very quiet, great consistant grind, solid build, smart design!
  • It has good weight without being too heavy to pick up and move easily.
  • Works great, powerful, relatively quite, great choice of grinds, and value for the money.
  • The only thing I might wish for is better storage for excess power cord.
Rancilio ROCKY HSD-ROC-SS Espresso Coffee Grinder with Doser Chamber
  • The Rocky grinder is so incredible. Tons of horse power and a consistent grind.
  • This thing is a TANK. It gets used all the time. I love this grinder. The adjustments are great. The quirks are still there but well worth the purchase.
  • This grinder produces excellent ground coffee. The grind size adjustment is high precision.
  • It's still a great grinder. It's heavy and seems to be built well.
  • This grinder does a great job and makes excellent espresso grinds. I would highly recommend this for the casual espresso drinker.
