The operation is very simple: fill water in the accessible from each side water tank, fold the coffee filter container to the side and insert the filter, giving coffee to then adjust whether it may be a small or large cup, press button ... Done is the delicious coffee. A Mettes feature is the automatic shutdown function.
Another praise worthy addition to the Descaling the included thermos. Namely This provides a pressure seal, which only opens when you press the lever with your thumb. The pot is always closed and the coffee stays hot for a long time, since hardly any heat loss occurs when pouring. 5 stars from my side
