The device does what it should. It works quietly and reliably. However, what is annoying, is the illuminated steam nozzle - it interferes with sleep, despite the fact that the light comes at a very dark blue (the previous model had a bright white on board). It is probably only cost a few cents more, to allow the user to select whether the lighting is switched on or off. Because of this small inconvenience therefore only four stars - from the functional point I would have given five; in dry areas - especially if you travel a lot - and speech professions a true blessing.
