This is the best and largest grinder that Mazzer makes. No other grinder is comparable. The Mazzer Robur grinder dials in your desired dose and grind size to perfection. The stepless grind adjustment is the best in the business at getting the exact grind size that you are looking for and keeping it stable. When I was cleaning the grinder I rubbed off some of the paint on the model plate. You can compare the two photos which are before and after cleaning. The Mazzer Robur Electronic is a low rpm, high output conical burr espresso grinder. The low speed conical burrs provide a superior grind quality and combined with the automatic cooling system drastically reduce heat build up compared to typical grinders. Additionally, the Mazzer step-less micrometric grind calibration, programmable timed doses and simple, and intuitive user interface make this the an uncompromisingly great grinder, capable of producing a superior espresso.
