There are things that I no longer want to do without. The device Krups F 230 we paid our son. Before about 30! We bought the (almost) same unit for our financial years. It works without any problem even with regular use. Here you can make the company Krups only a compliment. Household items that already work on a generation, are already an exception. From a cost perspective, I can only recommend the device because is connected to preparation of cooked very little water and therefore low energy costs. The cleaning is easy. It is useful from time to time the addition of vinegar to prevent calcification.
