This grinder lives up to its name, it won't wake your partner at dawn, a promise owners confirm it actually keeps. The grind quality punches above its price point, producing fluffier, more consistent espresso grounds that dial in predictably. It's designed as a hopper-fed grinder, but most buyers single-dose it, which means you'll be pumping bellows and living with 1-2g retention unless you add mods (tilted stands, aftermarket hoppers, bigger adjustment dials are all common). If you want affordable, quiet espresso grinding and don't mind tinkering with workflow, this is a smart entry point; if you need zero-retention single-dosing out of the box, look at the Mignon Zero or DF64 instead.
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.
