This is the hand grinder for people who treat coffee like a craft and don't mind working for it. Four ball bearings, stepless adjustment to 0.01mm, and grind consistency that rivals electric grinders at twice the price make it a precision tool in a category full of compromises. The catch cup is absurdly small and tips the grinder mid-session, you'll crank 90 times for a single espresso dose, and the optional pour-over burr is a documented gamble (some worse extraction, astringency, and alignment issues requiring manual shimming). Buy it if you want the most mechanically refined hand grinder available and value grind quality over convenience. Skip it if you grind for more than one person or need speed in your morning routine.
