## What reviewers say

**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.)

**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.)
