I think the last electric equipment I bought, was a water heater. What I really appreciate about the device is, that the water boils very quickly. An other advantage is, that you can put 1.7 litre in it, which is a lot of water. What isn't good at all, is that althought I descale the water boiler regularly, there are always some small pieces of lime in the boiled water, which in the end end up in my cup.
