Sonic Alert SB300 Sonic Boom Loud Vibrating Alarm Clock with Large Display
I'm deaf in one ear and an extremely deep sleeper. Lying with my good ear against the pillow, I've slept through fire alarms, medical emergencies, incessant phone calls, etc. After I slept straight through a midterm exam despite setting four different alarms in my room, I started losing sleep at night because there seemed to be no way to predict when I'd wake up the next morning. The Sonic Boom alarm clock has been a blessing on my nightstand for four years. Since then, as long as I've set this alarm, which uses A/C power and has easy-to-press buttons for setting the time and alarm, a snooze button, and a vibrating disk that slips under my pillow, I've never overslept again. Other features include an alarm tone that can be adjustable in volume and pitch, depending on hearing needs, and a flashing display, but I don't bother with either. The minor earthquake under my pillow is all I need. It's not very cute and it doesn't come in purple, but it lets me rest easy.
