The device is functional and easy to use. Have the unit of Bomann bought because my parents (90 years old) need an easy-to bediendes device without digital bells and whistles. The previous model of my parents was a unit of Clartronik and has gone kaput after about two years (has puff away). I hope that the new device is keeping longer, it is in fact identical. I hope that the old device was Clartronik a blip in quality.
