... Raises the alarm again and again at night and indeed about to 1 clock. Then he rattles even 24 h, although the alarm had before that displayed the precise time. This is quite annoying, especially when you have to get up at 5:45 clock again, because you will be awakened by the rattling every night. Whether it was just a malfunction, I can not say. Previously I had a similar alarm clock but by TFA Dostmann - who had held over 3 years and is only broken because I had thrown down him. I have the alarm ow sent back and bought another, which is optically not as nice as this (deshalbt least 2 stars), but the alarm has digitally adjustable and me especially not wake each night.
