We have for several months now in this coffee brewed at the beginning Gebrauch.Sie quickly and very quietly, but what happens to every good coffee machine times, they calcify. Then it is just as loud and röschelt to himself, like any other machine they auch.Ist Once decalcified, it's back for a while, but then scaled up (like any other) at shorter intervals. For the better: Great looking and easy to clean housing. Handling I personally find very good and easy. The lid of the water tank and the filter cartridge can be easily matched to lose weight to be cleaned. (Previously I had a Krups, and since screwdriver and hammer were needed to disassemble :-))) The stainless steel pot is just great. The new closure technique is used to, but very good. No drops and long Kaffee.Kein hot hassle misjudged the cover (I know too well, from other thermos flasks with screw cap). Shutdown works fine ... and now I'm coming to the Nachteilen- Negatives: The coffee has no off switch! That is, once turned on, you can not stop, unless they are separated from the power it! And then a minus zur Kanne: Your steel use is relatively fast brown and very unsightly. Scrub all is in vain. And I now give the tip, as it is clean again: Just let a dishwasher Tab into it, boiling water and 1 hour to act. After the pot from the inside is spotless again and looks like new. Conclusion: I would buy this coffee at any time.
