Consistenly lets me down

I am a Paramedic / Firefighter and this alarm is very inconsistent. Sometimes it works and sometimes it doesn’t. I always end up using the IPhone’s alarm as a backup as I can’t trust this to actually work at 4:45am. Yes, I know to leave it in the alarm clock mode prior to going to sleep. The fact that I can sometimes wake up to my favorite music is the only reason why I continue using it. I have had this for 3 or 4 months and keep hoping that they fix the bug.
