What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Mignon Specialita
Only one whitelisted hands-on tester (Tom's Guide) reviewed this exact grinder; coffee blogs like Coffee Chronicler and Home Grounds were excluded as non-testers. Tom's Guide's Peter Wolinski ran a long-term hands-on test and calls it a fantastic, tank-built espresso grinder praised for low retention and consistent low-static grinding, but flags a messy high-angle chute, single-brew-type focus, and pricey, hard-to-find U.S. availability. No lab measurements or benchmark numbers were reported. (1 sourced review, 1 lab-tested.)
Praised: Fantastic, durable full-metal build quality; Low retention makes dialing in near-instantaneous; Consistent, even grind with little static or clumping.
Flagged: High-angle chute causes messy worktops; Long adjustment throw makes switching brew methods awkward; Pricey and hard to find in the U.S..
C40 MK4 Nitro Blade
Only one whitelisted hands-on reviewer survived verification: Tom's Guide, which lab-measured grind uniformity (Kruve sieves), retention (scale, before/after) and grind speed, and named the Comandante C40 MK4 Editor's Choice. Every quote and measured value in this entry was confirmed verbatim against the fetched article. Verdict: best-in-class hand grinder for consistency and low retention, but slow to crank at fine settings and very expensive. (1 sourced review, 1 lab-tested.)
Praised: Consistent, uniform grind across the full range (verified via Kruve sifter test); Low grind retention, averaging 2.75%; Exceptional build quality and ergonomic body/handle.
Flagged: Very expensive (~$277-$323); Hard and slow to crank at finer settings (below ~20 clicks); No indicator showing the current click/grind setting.
