The Smeg KLF04 variable temperature kettle allows you to choose from a number of temperature settings between 50°C to 100°C to customise the water temperature, depending on your favourite tea - green, fruit or oolong for example. The keep warm function enables water to be maintained at the selected temperature for up to 20 minutes. The kettle opens gently when you push the lid in the designated place. Smeg kettles are bound to make a statement on any kitchen worktop, and they boil water very well.
