We had a simple Senseo - machine with which I have been very satisfied. Of course, in the bar-duo the biggest advantage is that you really super delicious, fresh milk froth gets without having to do a lot for it. Press hose into the milk carton, button and off you go. The "structure" was easy and the service is almost self-explanatory and intuitive. I personally like the design well. Simple and elegant. After about 400 cups then lit the "Calc" button, but also descale is easy, the 1st time with manual. This model can be set during the coffees and the amount of coffee, so if you macchiato Latte bit more or less coffee would. And I'm the coffee taste of Senseo anyway. The only thing I do not like is the relatively small water tank, but the benefits outweigh.
