Great features, efficient, but noisy
4/5
It's an excellent kettle: it boils water very quickly, the variable temperature settings are great, and seem pretty accurate, for green and other teas, and the ability to heat just enough water for one mug means you don't waste energy on heating more water than you need.
The only down side is the noise if you are boiling water. If you set the temperature to eg 80C it's totally fine. But set it to 100C and it sounds like an aircraft taking off!
Overall it's a very good kettle but don't try to have a conversation or listen to the radio while boiling water.
