Smeg KLF04 Variable Temperature Kettle

If the kettle has to look the part on show, the KLF04 is the pick. Beyond the 1950s-inspired styling and broad colour range, it is a capable performer: manufacturer specs list seven temperature levels from 50°C to 100°C, a keep-warm function up to 20 minutes, a 3kW element and a 1.7L capacity, plus a removable stainless-steel limescale filter and a two-year warranty. Its wider low-end range (down to 50°C) even edges the Bosch on paper. It ranks third rather than higher because value is its weak point: at an indicative £140, rising to £189.95 direct from Smeg, you pay a heavy premium for the design over the near-identical functionality of the Ninja. Choose it over the Dualit below if aesthetics and colour-matching matter more than long-term repairability.
