Data from official source

The Duo pairs its grinding unit with two interchangeable sets of 83 mm flat burrs, one for espresso and one for filter methods, covering both without recalibrating the same set each time. The body is aluminium with real oak trim; the filter set can be bought together with the grinder or added later, and swapping burr sets takes less than a minute.

Grind adjustment runs on a continuous, click-free knob, with no numbered steps: you choose the setting and pour beans into the funnel right before grinding, since there's no hopper holding them between sessions. In the box are a 58 mm grind cup for dosing straight into the portafilter, a socket driver and a cleaning brush. The design is straight-through: nearly everything that goes into the burrs comes back out, with no residue left behind.

It suits someone who wants to move between espresso and filter without switching grinders, not someone after a hopper they fill once and leave topped up for days.
