Our Gigaset 4010 went from one day to the next is no longer. Despite mobile phone a landline phone in my opinion, is still a "must". After appropriate research on the Internet by an equivalent phone we were successful at S670. The Gigaset S670 you get a solid device and the server and menu navigation is logically structured, you need to be reasonably technically versed person no manual. The memory is large enough, the permanent lighting is a matter of taste, but you get used to it and the energy-saving function ensures "peace of mind". The voice quality is perfect - even in handsfree mode. Minus point is the minimum selection of rings. You could be bigger or different. I agree with one or the other previous speakers. I would buy this phone again immediately.
