Our verdict
41 grind settings, redesigned anti-stall ring and an airflow cup. It earns a 4.6/5 because, after measuring 19 s and pushing it through our standard 40-shot protocol, it does what it claims — consistently and without drama. Best for: Design-first kitchens that brew espresso and pour-over from one grinder.
