TRADEOFF
The compromise to price in
The grind-by-weight workflow is espresso-focused, costs more than timed Mignon models, and includes a 58mm funnel; smaller baskets need a separate funnel.
FIELD-LEVEL EVIDENCE

KNOWN LIMITATIONS
What the record cannot prove
- The included dosing funnel is 58mm; Clive lists a separate 53mm funnel for smaller baskets.
- Dose consistency and 64dB claims are manufacturer or retailer statements, not Espresso Receipt observations.
Published specifications do not prove taste, noise, durability, thermal stability, mess, or real-world speed. Those require a documented physical test.
