Expert Analysis
The Fellow Opus ($195) and Eureka Mignon Crono ($229) are entry-to-mid-level grinders bridging the gap between budget and serious. The Opus uses 40mm conical burrs with 41 steps and 1.0g retention at 3.2 kg. The Crono uses 50mm flat burrs with stepless adjustment and 1.0g retention at 5.0 kg. The Crono's flat burrs and stepless adjustment are superior for espresso — infinitely fine adjustments versus the Opus's 41 steps. The Crono's 50mm flat burrs produce more uniform particles with better clarity than the Opus's 40mm conicals. The Opus's modern Fellow design and anti-static technology are appealing aesthetically.

The Opus is better looking and more versatile for those who brew both filter and espresso.
