Handy alarm clock: lightweight, compact, stable, easy to adjust (you can throw the notice as soon as you read it and it is not very long). Noise or light disturbs sleep but the possibility by simply pressing the top (easy to find in the dark) to momentarily illuminating to see the time at night (big enough characters that are legible even for most usually people wearing glasses). Possibility to choose the snooze function for repeated ringing after a few minutes of respite. Only complaint: the ringing is not super nice as often (this is the classic of classics), but all his other qualities allow to pass it.
