WHY THE PRICE IS JUSTIFIED

The money buys machined aluminum, a triple-bearing axle, 65mm bespoke burrs, a low-speed geared motor, a static reducer and a real chute knocker—not cosmetic electronics. Option-O specifies sub-10-micron tolerances on critical components; independent testing and retail measurements support very low exchange. It is expensive, but still below true premium-flat-burr pricing.

MATERIALS

Body and grind chamberCNC-machined 6061-T6 anodized aluminum

Rigid, vibration-resistant structure supports alignment and survives repeated servicing.

Burrs65mm hardened-stainless-steel Mizen conicals

Large, bespoke geometry balances clarity, body and grinding speed.

Shaft supportMetal triple-bearing assembly

Constrains shaft wobble and protects concentricity under load.

CRITERIA

9/10

Grind Consistency65mm Mizen geometry gives balanced clarity and body across espresso and filter.

10/10

Retention ControlStraight path, static reducer and knocker; claimed average dynamic retention below 0.1g.

9/10

Dial PrecisionLarge stepless, calibratable dial spans espresso through coarse brewing.

10/10

Alignment StabilityTriple bearings and critical components machined to under 10μm tolerances.

9/10

Burr SystemLarge 65mm bespoke conicals; cross-compatible Casa platform.

8/10

Reliability & RepairAll-metal core and accessible chamber; younger service history than Mazzer or Baratza.

9/10

Noise & HeatLow-speed 140-RPM architecture is quiet and limits dose-scale heating.

IDEAL FOR

·One grinder for espresso and filter
·Light-to-medium roasts
·Design-conscious small kitchens
·Low-retention single dosing

NOT FOR

·Hopper-based dosing
·Commercial throughput
·Lowest-cost buyers

DESIGN & ERGONOMICS

Exceptionally slim 3.5-inch body, quiet motor, top bean port, magnetic cup and push-button knocker. The large front dial is readable and calibratable; the minimalist form wastes little counter space.

LONGEVITY

Excellent material basis and easy chamber access. Motor and gearbox are engineered for home duty; parts support is credible, though the model lacks decades of field history.
