What we like
- Widely regarded as the benchmark hand grinder for a reason — build quality is exceptional
- Individually calibrated click wheel means real, repeatable precision between grinds
- Near-zero retention and a crank action that feels smoother than nearly every rival
What we don't
- Expensive for a grinder with no motor, and the price draws fair criticism on that basis alone
- Stock burr set favors pour-over and filter more than it favors fine espresso
- Like any hand grinder, it asks real time and effort per dose
