KitchenAid KEK1722WH 1.7-Liter Electric Kettle
For the most versatile and feature packed kettle here, you'll want the KitchenAid KEK1722WH 1.7-Liter Electric Kettle with LED Display. With six separate temperature settings between 122 degrees and 212 degrees, you will get the absolutely perfect water temperature every time. The LED readout lets you see the temp setting, and batteries will keep it lit even when you take it off the powered base. The water fill window is blue light backlit, and with 1440 watts of power it brings the water up to the minimum temperature in about one minute, with six minutes to a full boil. This is the most expensive kettle here, but if you want bragging rights (or just the benefit of variable temperature selection) then this pick deserves your consideration.
