Have the Opis 60s cable bought a few weeks ago and am very satisfied. It was to connect without problem (are all sorts of plug in) and the ringing is really special. The mechanical rotary dial makes a very high-quality stable impression and running smoothly. The handset has a very good sound. Since my DECT can not keep up. Something disturbing is the lack of display. Lifting is thus again the real surprise, but I've known before. For me, the decision to buy was the design and less functionality. All in all class product, therefore 5 star.
