Perfectly adapted to the Siemens series A range; original connector; Cable length just right. Good battery life: about 4 days without rest on the base at a rate of 60 to 100 minutes of calls a day. And cheap. It is much better than changing phone !! Think about making some complete charge / discharge cycles initially to optimize the battery capacity and never leave permanently in charge (batteries do not like and it reduces their lifetime). So basically, do place the handset on the basis that when there is need to recharge the battery.
