Starting from $19? And I assume those are American dollars? Wouldn't it be more cost effective to buy a loud alarm clock and place it across the room? If I buy two and set their alarm time 3 minutes apart, aren't I effectively doing the same thing cheaper and with no risks?

I'm not trying to shit on your idea, but I don't understand the consumer value proposition.

Fair question on price! But if loud alarm clocks across the room worked for heavy sleepers, this wouldn't exist. I've tried every alarm hack - the human element and social pressure is what makes the difference. Plus $19 occasionally vs missing important meetings/flights is worth it.
