Serious Eats' pick for coffee geeks, with very consistent grinds and a solid build. But Food & Wine measured it at 88 dB and found it less reliable at its coarsest and finest settings, and Wirecutter dropped it because the ESP Pro offers more for $50 more.
Top complaints
- Very loud
Food & Wine measured 88 dB and says it will likely wake every sleeper in the house. Noise level is mixed on Amazon.
- Fiddly hopper assembly and chute chaff
Serious Eats' biggest gripe is that the gasket, ring and hopper aren't intuitive to assemble. Chaff builds in the chute and falls out when you remove the bin, and static takes about 40 seconds to dissipate. Good Housekeeping also notes extra setup steps.
Source: Serious Eats, Good Housekeeping - Weaker at the extremes; pricey
Food & Wine found the grind got motley at the coarsest end and couldn't dial in top espresso at the fine end. Value and durability are mixed on Amazon, with some units breaking in under two months.
What owners love
- Very consistent grind
Serious Eats found so few fines its scale couldn't register them. Good Housekeeping saw clearly different fine, medium and coarse grounds, and consistency is positive on Amazon.
- Solid build and repair support
Food & Wine notes stronger metal parts, a robust DC motor and nearly every part sold separately. Serious Eats lists a 2-year warranty.
Source: Food & Wine, Serious Eats - Handles batch after batch
Good Housekeeping ground several batches without noticing heat, and Food & Wine found little retention after cleaning.

What experts say
- Serious Eats: Best grinder for serious coffee geeks; gripes are fiddly hopper assembly and chaff falling from the chute.
- Food & Wine: Best large-capacity grinder, but very loud (88 dB) and less reliable at its coarsest and finest settings.
- Wirecutter (NYT): Former upgrade pick, still a great grinder, but the ESP Pro offers far more for about $50 more.
- Good Housekeeping: Best to prevent overheating; cons are extra setup steps and the price.
