Another plus is the pleasantly quiet alarm. I do not know whether he is louder with time, because I turn it right and get up. But in any case he wakes me only and not the whole house!
When the alarm is silenced I find convenient that I either can press if it (wide key), then repeats it alarm repeatedly. Or I press one of four (adjustment) buttons on the front - no matter welche- and the alarm is no repetition, but wakes up the next day back to normal.
That one gets even in morning twilight down slightly without the alarm clock falls down or is completely adjusted.
So for me a success all around device that does not have a lot of bells and whistles, but reduced to the essentials Funtkionen are easy to use, to design anything I say, that's a matter of taste, I like it.
