You see, I am the kind of person who can literally sleep through an earthquake (true story). I've slept through smoke detectors going off (bad news for me should I ever find myself alone in the house while sleeping during a fire). My attempts to wake up earlier than normal are futile, I set several alarms to go off at different times and I sleep through them all. And not only am I nearly impossible to wake up, but I am also the definition of "not a morning person".
I bought the alarm after searching for "loudest alarm clock" and read the rave reviews from people who were also difficult to rouse. I take the alarm for my first official test run tomorrow morning. I'll keep my empty audience updated on the result.
