Fellow's $200 all-purpose grinder is a pour-over specialist in espresso clothing. The original clogged relentlessly, coffee caking on chamber walls until owners either deep-cleaned weekly or upgraded within two years. The current Opus 2 solved retention, but espresso remains its weak spot: recommended settings choke most machines, so you grind coarser than the dial suggests and still get less consistency than a DF54 or Eureka Mignon Zero at the same price. Buy it if pour-over is your main game and you want something compact and handsome on the counter. If espresso matters, you'll outgrow it fast.
This $4,000-$6,000 flat-burr grinder pulls flavors from beans that mid-tier machines leave behind, delivering micron-level precision and clarity that can genuinely transform a filter brew. The catch is operational friction: it occasionally stalls mid-grind on certain coffees, blows its own fuse if you press buttons at the wrong moment, and demands more cleaning ritual than a $300 grinder that delivers 90% of the cup quality with none of the fuss. If you're chasing that last 10% of clarity in filter coffee and the price feels like an investment rather than an expense, this is your endgame. If you just want great coffee without the ceremony, spend the difference on better beans and skip the quirks.
