WHY THE PRICE IS JUSTIFIED

NOT FOR

·tight under-sink cabinets
·budget-led replacements

DESIGN & ERGONOMICS

The removable baffle, sink/cupboard-mountable air switch and blade-free throat are unusually thoughtful. It is visually discreet but needs substantial 344 mm cabinet height.

LONGEVITY

Eight-year warranty in its UK market. Stainless wet components and simple mechanical grinding favour durability; the large enclosure makes professional fitting sensible.
