works fine.
The machine is fine. The instructions are translated from another language, probably German, and the translation is less than perfect.  they also leave some questions unanswered, like how to vary the volume.  Fortunately, a follow-up email clarified how to use the single volume button. I might wish that the display was dimmer.  I find that I wind up covering it so that it is less obtrusive. some of the sounds are distracting, like the dropping water sounds.
