Waking Alarm

What does it take to wake you up in the morning? Would the rip of a chain saw do the trick?

I know for fact that this will definitely not be on my Christmas list this year. A regular alarm clock is already annoying enough, wouldn't you think? This new alarm clock has some pros and cons to it. Its loud enough to wake you up in your deep sleep and you're able to place it either under you pillow or mattress and it will shake you awake. The alarm clock has a probability of creating anxiety and cardiovascular problems.
