The smooth rounded design has a 1.5 litre capacity and thanks to the double wall construction will keep boiled water hotter for longer as well as reducing noise whilst the water is boiling (which the 3000w concealed heating element will make quick work of). The comfortable, soft grip handle accommodates the button which releases the soft-open lid and a back-lit water window allows you to boil just the desired amount of water needed. The kettle sits on a 360° base allowing for easy left or right handed use. The base also features the adjustable temperature setting slider which gives you control over the temperature you want your water to reach - from 50°C up to 100°C. This is perfect for when you are infusing delicate teas such as green tea which would be ruined if you poured on boiling water, whereas a coarse Assam leaf will benefit from a hotter temperature water A stylish temperature gauge on the side of the kettle wall means you can see the exact temperature of your water even when the kettle is removed from its base. The kettle comes with a KitchenAid 3 year guarantee. Plastic inside.
