American Inventor Spot blog has a neat list of the things you really need to buy for college.
This one is the Emergency Siren Alarm Clock, guaranteed to wake up everyone in your entire dorm!
Never miss a class or an important test.
Just set this "sure to wake you up" siren alarm clock with blaring lights to turn on every morning for your 8:00 AM class. Make sure to set it early to give you lots of extra time to get ready. Don't be afraid to let the whole dorm know about your morning class since they should be up and studying anyway. Your friends will be especiallay happy on weekends mornings when you set it for your sunrise jog.
