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 grinder delivers solid burr quality at a budget price for pour-over and drip, but it's fundamentally unsafe for long-term use. Grounds migrate into the motor housing over months, creating a fire hazard that multiple owners have independently documented, and the extreme retention means stale coffee mixes with every fresh batch. If you're brewing coarse methods and never touching espresso, it works fine short-term, but the safety issue and inability to grind fine enough for espresso make it a poor investment for anyone who might expand their coffee setup or keep a grinder for years.
