"Ring" Alarm

So, I know we all have those times when we do not wake up to our alarms for various reasons. Lately this has been a huge issue as a college student because, after staying up until three or four in the morning, it gets difficult to wake up.

 

This is an alarm clock that wakes you up by a ring that vibrates on your finger. If you share a bed with someone, you can set the alarms to different times and not have to worry about the buzzing waking each other up!
