Why we love it

The hand grinder that stops being a compromise. External adjustment means you dial grind size without dismantling anything, and at 20 microns a click you can actually chase an espresso shot rather than approximate it. The K burr is fast — a filter dose takes well under a minute — and the magnetic catch cup means grounds go where you point them. It out-grinds most electric grinders costing the same.

Pros

  • External dial, over 100 clicks at 20 microns — espresso-capable precision
  • K burr grinds fast for a hand grinder
  • Magnetic catch cup holds 35 to 40 g, enough for a full brew
  • Folding handle plus a travel case
  • Tool-free dismantling for cleaning

Cons

  • Costs more than several capable electric grinders
  • It is still a hand grinder — espresso doses take arm work daily
  • More adjustment range than a filter-only brewer will ever use
  • Heavier than the travel grinders it shares a shelf with
