No single component dominates
~1 in 2 long-term reports mention a failure — the highest failure rate of the 6 coffee grinders we track, and well above the category baseline of 14%. Most components implicated involve the burr assembly and associated fittings (quick-release knob, burr holder, burr ring, burr shaft). Onset typically falls between 2 and 5 years of use, which is longer than the category median of 7 months before first failure. Warranty outcomes lean slightly toward resolved, but with 12 resolved cases against 8 unresolved, a meaningful share lands outside coverage.

~1 in 4 long-term owner reports mention a failure, most often the grinder, typically inside the [2,19) month window. Warranty outcomes lean positive in the reports that mention one.

These are the share of long-term owner reports that mention a failure, not the share of units that fail — owners with working units mostly don’t post.
