Operation with display and rotary knob simple or cumbersome? Experience shows that sometimes fewer buttons and a colour display are not necessarily easier to operate. Even if they look ultra-modern. My first thought was: What? A coffee machine with a colour display? My question: Is it easy to operate in everyday life or rather fiddly? (Example: in the morning at half past five with half-open eyes...) Once the machine is set, do I not need to use the rotary knob and the display so often? I don't always want to have to turn and press and turn until I have my coffee/cappuchino.... :) Thank you very much.
