"It's a $12 appliance that smashes beans; set your coffee expectations accordingly."
'Grinds enough coffee to brew up to 12 cups' simply means the container holds about 85 grams of beans, a standard input for a full pot of drip coffee. It is a capacity measure, not a performance guarantee.
This is for someone who wants to upgrade from pre-ground coffee for the lowest possible cost, and for whom 'freshly ground' is more important than 'ground well'. It also serves as a cheap, dedicated spice grinder.
Anyone using a French press, pour-over, or espresso maker should skip this, as those methods require a particle consistency this machine cannot achieve. If the words 'flavor notes' mean anything to you, invest in a burr grinder.
