Now I already own several Bialetti stove. Bialetti is the most recognized brand for mocha maker in Italy. It is very well made and by the polished aluminum beautifully. Therefore, never put in the dishwasher. The espresso succeeds very well with it. Kollengen, with a fully automatic get a better result under any circumstances. It is important, therefore, that one can climb the coffee slowly over moderate heat. A great advantage is also that the jug can be cleaned easily and thus no coffee residues from the last time, affect the result. That's just a great disappointment in the fully automatic machines. Cleaning or not, as more and leave remnants that affect the taste. Millions of Italians can not be wrong ... In addition, it is also much cheaper than an espresso machine
