Simple, robust phone with great stand-by time

Have the phone purchased, as it has promised a 4-week standby time. The pledge was redeemed. It is also very robust (drop tests of shirt and jacket pockets survived). One can also "sit on it" (pockets). Of course it is not high-tech. There can be no import ringtones and it has no other gimmicks. But for Telefonierenn and SMS write very well usable.
