Disastrous (continuous leakage)

After some time, the kettle (not very practical because it takes moreover place the receptacle part to perfection if we want water flows inside) becomes completely unusable. Water limestone eventually prevent water from flowing into the carafe part despite every precaution so that we are left with perpetual flooding. The system is therefore impractical and its lifetime is not long because after a year and a half it is simply unusable.
