The sonic alarm has a vibrating pillow, flashing light, and adjustable tone for 120 db speaker. The alarm clock is set to go off full tilt right by my head, but my roommate would still have to run in and yell at me to wake up. It usually takes anywhere from 30 to 45 mins of that before I even start to regain consciousness. I hate you loud ass alarm clock. It would either wake you up or give you a heart attack! It would be the bad neighbor for half the county with one of these.”]
