## What reviewers say

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. (Based on 1 review, 1 lab-tested, 2025-03-14.)

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; Militaristic branding feels cringe; wristband accessory is useless.
Disagreement: No cross-source comparison was possible: only a single whitelisted hands-on review (Tom's Guide) survived verification, so no agreement or conflict between sources could be established. All claims here rest on that one tester.
