I drink a lot of tea and coffee daily and after a few months of heavy use my first electric kettle stopped working.
One has to have an electric kettle. It's so energy-efficient and fast. - right? So I bought my second electric kettle.
This time it could heat water one cup at a time - it also could produce water at the exact right temperature for green tea. At least - until it's cables started smelling and we got really worried that it might start to burn.
