The alarm clock was a gift for my 82 year old mother. She wanted a small, easy to read even in the dark alarm clock which does not fall equally on contact. This should arouse an alarm clock, is in the nature of things. Size, readability, use of illumination in the dark without the need to touch the alarm, everything super! Unfortunately, the clock is its eigentlichem purpose, awakening, at least for the elderly, do not do justice. The alarm is simply too low and also can not be changed. Also a request from the manufacturer confirmed this. So who is awake by silent alarm, the alarm clock is this a really good buy. Who but loud or even to wake up several alarm clock needs, is the sleepy here in any case.
