If you put water in this it gets hot quickly
5/5
If you put cold fresh water in this and flick the little switch on the side it becomes hot really rather quickly.
You don't even notice it is happening. One minute stone cold, and the next it is hot enough to make tea or coffee with.
My wife even makes some sort of potion by adding a bag of 'detox' to a mug and pouring some of the hot water in. This tastes like the bottom of a hamster cage, but if you like that sort of thing, it works for that to.
Seriously though, this is a great kettle: It is quiet, it boils quickly, is a decent size and looks fantastic.
