The trick is to get one with a buzzer that is loud enough to hear and annoying enough that you just have to shut it off. On my phone, I downloaded a sound that is so loud and so screeching that I can't ignore it. I also use it as an alarm in the morning. I get up in self-defense. I never hit the snooze button because one shock like that in the morning is enough.
