I opted for this alarm, because it lt. To tick the previous reviews very quiet and silent. Unfortunately, that was a mistake. Although some clock ticking louder decided, really quiet, he is not yet. So he was banished from the bedroom. In the morning he rang then also good and rang and rang ..... Sometime I am then annoyed out of bed and had identified him. He stops by itself probably only if the battery is empty. should that be so ? probably not. The alarm clock is small and cute, not to use otherwise for me.
