Fellow's second swing at a pour-over grinder fixed the Gen 1's range problem and delivered what the light-roast crowd actually wanted: whisper-quiet operation, tea-like clarity with washed coffees, and a workflow so clean you'll forget what static cling feels like. The catch is narrow: medium-dark roasts taste dull and flat, the hopper forces you to grind in shifts for batch brewing, and a pattern of motor failures around ten months of daily use means longevity isn't guaranteed despite the premium price. If you brew single light-roast pourovers and prize clarity over versatility, this is the grinder to beat. If you want one tool for all roasts or need it to last five years without drama, look elsewhere.
Option-O built its reputation on a specific bet: that stripping away fines would unlock clarity light-roast obsessives had been chasing for years. The P64 proved that bet, then got replaced by the P80 with bigger burrs and tighter tolerances, so you're shopping a discontinued model unless you find used. What you get is exceptional flavor separation and near-zero retention, but these grinders pull thin, bright shots that read beautifully yet lack the syrupy body traditional espresso drinkers expect. If you brew fruit-forward naturals and want to taste every fermentation note, the Lagom family delivers; if you make milk drinks or prefer chocolatey medium roasts, a conical grinder will serve you better.
