The coffee I have now for 4 weeks of usage. The filling opening is really so narrow that most things go wrong. The coffee is pretty hot after brewing, but only when the jug is full. At 2 cups he is lukewarm. And what I have to complain about yet, it fits into the thermo-pot coffee less pure than in a normal ordinary pot, even though the water tank is designed for more water. If one were to carryout container, the jug will overflow. Comical construction.
