As I call only rarely by landline, this device meets my requirements. I have stored a few numbers. I was lured the design. Unfortunately, the ringtone in the volume is too little variable, I personally would have liked a quieter level available (there are only 3 levels plus "rising", but that will end up shouting loud-my poor neighbors when I'm not there) , Very practical is the LED that flashes clearly visible when a call has been made in the absence. Something is very disturbing, and that will be the reason that I will decommission the phone sooner or later, that when the battery has run empty, and you put the phone to charge at the station, a high-pitched load signal (consisting of 2 loud beeps) is repeated continuously until a certain level of charge has been spilled into the battery. This can be by 2 minutes at a time. My Nerves! You can not deactivate this tone! And if now comes the question, why my battery often is empty, where I but little telephone: I have from time to time travel business, the handset then turn off, take the station from the power supply, but of course the battery discharges with the time as normal. I would just not wasting electricity, if I am not there anyway.
