A revolutionary new grinding technology of simplicity, efficiency, and durability. This new mechanism has the outer burr rotate and the inner burr fixed, a truly revolutionary design; which doubles the efficiency of similarly sized grinders. Coffee passes straight through the grinder, vertically, and drops directly into the grounds bin or your portafilter. It has a macro/micro adjust for grind size, as well as 3 programmable settings for dosing. These combined features offers the user incredible repeatability.
