With a boiling speed of 1 minute and 55 seconds, the Kenwood kMix 0W21011065 Black boils water quickly. Use it to boil up to 1 liter of water, for making 4 cups of tea. This silent kettle produces little noise while boiling water. It has a detachable limescale filter that's easy to clean under the faucet. The filter stops limescale particles, so that they won't end up in your cup of tea. Measure the amount of water directly inside the kettle, with the volume marking behind the handle. You can easily return the kettle to the 360-degrees rotating base after use.
