The Opus is about electric convenience: single-dose grinding at a button press, low noise, standout design, and espresso capability via a hidden inner ring, handling filter well. The Kinu M47 Classic is about precision and durability: a solid stainless steel body machined in Germany, 47mm conical burrs, a 0.01mm bearing tolerance, a tactile stepless click ring, and a 10-year warranty — the build benchmark among hand grinders.
Grind quality and longevity favor the Kinu — cleaner, more precise espresso grounds and an effectively indestructible all-metal body, versus the Opus's fiddly espresso dialing and static at fine settings. The trade is manual effort and a 35g capacity.
Convenience and price favor the Opus. At $195 it's cheaper and grinds without effort, ideal for a daily home counter; the Kinu is for someone who values craftsmanship, a decade-plus warranty, and grind precision over speed and doesn't mind hand-grinding. Design appeal is high on both, in different ways.
Buy the Fellow Opus ($195) for electric convenience, design, and value. Buy the Kinu M47 Classic ($349) for heirloom build quality, longevity, and precise manual grinding.
