high quality operation simplicity manual complete and legible paper (not downloaded from the internet) remarkable autonomy thanks to the 2 AA batteries 1.200mA: autonomy over a week on standby and 3-4 hours before recharging communications, is widely 3 times more autonomy than comparable devices. the handset is a little thicker than others, but at least it does not slip from the hands. probably the best phone on the market without wire.
