I ended up doing something imagined otherwise. Because no matter whether medium freeness or very finely ground (very fine is even recommended in the description!) The result is always the same. It always come only half-full cups zustande.Und whether loosely filled or slightly pressed coffee. No Difference. Also, I have to the amount of coffee powder experimentiert.Kein success. Although the taste of coffee, but what am I supposed to with only a half-full cup of coffee. Cut to have a sample pad and give this coffee powder which yes the pad with the normal Senseo pod holder 1er provides a full cup of coffee, taken. Again nichts.Meiner opinion, a bad design of this Duck. The Senseo pumped and pumped. But in the first 6 seconds comes before any coffee. So true since something wrong with the Duck (at small opening or how or what?) Get as long to use it to the 500g of coffee are consumed and then reuse pads. Although costs a little more, but I get finally a normal full cup of coffee, as it should be, (and then wipe in the trash with the annoying Duck!)
