What you’ll regret
The grinder
~1 in 4 long-term reports mention a failure, most involving the grinder mechanism, motor, or sensors, typically within 2–19 months. Warranty outcomes lean resolved but a meaningful share land unresolved. At 23% serious failure, this is above the 14% baseline for the 6 coffee grinders we track.

The motor
~1 in 39 long-term reports mention a failure — the lowest failure rate of the 6 coffee grinders we track, and well below the category baseline of 14%. Motor is the most noted component (4 reports). Warranty outcomes are evenly split between resolved and unresolved, so coverage isn't a guarantee.
