The Dualit 72470 is more than just an attractive kettle, with a John Lewis exclusive output of 3kW , rather than the standard 2.3kW output. It boils a full kettle up to 40 seconds faster than lower wattage models, and this retro-look stainless-steel kettle has non-slip feet to keep it firmly in place. A concealed element ensures easy cleaning , while a twin water indicator gauge means you'll always know when a trip to the tap is required - which thanks to the hinged lid won't prove too much of a chore. The washable limescale filter ensures debris-free beverages, while the large, heatproof ball knob and finger-guard prevent accidental burning. A boil-dry safety cut-out also prevents damage caused by under filling. Finally, this kettle arrives with a 2 year warranty for peace of mind.
