The operation is the same as in our previous Gigaset that we went after many years break. Intuitive and simple, no frills. Are of high quality / service life convinced that's why we again opted for Gigaset. A minus point is there for ringtones. They are just cruel! As we found our old ringtone pleasant, so we opted for a "normal" "Ring-Ring" :-) Regarding the Dune model we have clearly opted for the design for it. It is really very elegant, fits comfortably in your hand and snaps (better than our old phone) very nice in the station.
