The handsets automatically connect to the base station, which makes the initial start-up very easy. The entries in the phonebook are stored in the base station and are therefore identical all handsets available. To take always act on all handsets. In my view, a very simple operation. The technique seems robust. The keys are clearly visible and big enough. The voice quality incl. Loudspeaker for free listening are very good. For those who prefer the simple commissioning and then the device would be used easily in everyday life, is well supplied with the KX-TG6823. I can only recommend buying.
