You won't sleep through this alarm. Sometimes the old way of doing things really is better.
There are lots of other alarm clocks on the market targeted at heavy sleepers
that require you to solve some kind of puzzle, or shoot a target, or retrieve some kind of flying propeller to silence the alarm clock. They all have the same major flaw, they depend on you being able to actually hear the alarm and wake up first. They are all useless if you don't wake up to silence the alarm in the first place.
The Sapphire India Twin Bell is loud
to wake you from a dead sleep and looks good while doing it. Your pay for this alarm clock is nothing compared to potentially losing a job from being late to work all the time.
