It's more than just a kettle, the cordless automatic water kettle changes color as water boils. Simply flip on the switch and watch the exterior color changes in three different beautiful colors: blue when cold/stand by, violet when water heats up, pink when boiling. It's simple, fast, and easy to use. The cordless automatic water kettle boils water twice as fast as microwave oven, perfect for tea, coffee, hot chocolate or instant soup. It also includes a stainless-steel floor that keeps water away from heating element, which means no build-up of mineral deposits. For safety, the unit's Strix controller provides boil-dry protection and automatic cut-off if it accidentally gets switched on without water. Great for kitchen, office, or dorm room.
