I can not alarm the abgewinnen so much except that he is really quiet, no ticking etc ... The light is very weak, is only present as long as you hold the button down, is not as convenient when adjusting ... and a precise time setting works only with luck, a full hour is fine, but then it will be difficult, for example, 6:30 is sometimes even 6:40 or before 6:30 ... District before or after is genuine happiness, for safety I need a second alarm clock if need be on time. I've now tried a couple of weeks, but an accurate alarm I not get out, except as I said, a full hour.
