"It delivers the user experience of a $150 grinder with the grind quality of an $80 one."
The 'stainless steel conical burrs' crush beans between two cone-shaped surfaces for a more uniform result than a blade grinder. This means less silty 'fines' in your cup, but it will not produce the consistent powder needed for true, unpressurized espresso.
This grinder is for the person upgrading from a blade grinder who wants better coffee without a fussy, messy process. It prioritizes daily convenience, intuitive design, and cleanliness for drip, pour-over, and French press coffee makers.
Aspiring espresso makers should look elsewhere, as this unit won't produce the fine, fluffy grounds required by unpressurized portafilters. Coffee purists who single-dose expensive beans will be paying for a large hopper and features they will not use.
