Conical Burr Coffee Grinder (All-Purpose)

127 sources · limited data · updated June 2026

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.

The generation that matters

This product isn't one story — here's how each era is regarded.

Opus Gen 1

2023, 2025

Mixed

High retention, reliability issues (burr failures, clogs), and inconsistent espresso performance. Many upgraded away after 1-3 years. Praised for pour-over but criticized for espresso grind quality and durability.

Opus Gen 2 / Opus 2

2025, present

Solid

Described as solving retention issues and offering better espresso capability. Early adopters report good value at $200, easier dialing, and improved workflow. Some pre-order delays and isolated DOA units noted, but overall reception is positive.
