Clocks Alarm tells me when I've missed an alarm...!!!
FFS!
I want an alarm clock that goes off at the right time!!!
I DO NOT want an alarm clock that fails to go off.
I ABSOLUTELY DO NOT want an alarm clock that tells me 5 minutes after the fact that it's missed an alarm...
Just take the alarm clock out if it doesn't work - it's better to have no alarm clock, than an alarm clock that's broken. See attached pic
