I have been looking for a cordless phone for a while and the Siemens C150 with the C1 handset is really what I was looking for. There is anything I need and more available from good phonebook +10 quickly accessible numbers, internal calls, SMS, various settings for audio and general... so when by mistake I drove over one of the two handsets (must have left it on top of my car and then driven off?!) I quickly reordered this one as I do not want to have to buy a whole new set again, should I leave the other one out in the rain (another favourite of mine) - the range is just so good! Only wished it had an audible alarm when there are messages and yes when I leave it out on the car or in the rain ...
