Query: Wake up on time, finally!

The Association of Medical Professionals With Hearing Losses recommended this alarm clock. Like other healthcare providers, I had not been able to hear my "normal" alarm clock, and was frequently late for appointments, or missed then completely. The Sonic Boom Vibrating Alarm Clock will not dissapoint. For the Deaf, the vibrating component shakes one right out of bed. The adjustable alarm sound is so extremely loud that turning it up risks even greater hearing loss. The Federal maximum noise level is 120 db, and this alarm tops out at 110 db. Explosive. This is the Gold Standard for the Deaf and Hard-of-Hearing. I recommend this alarm clck without any reservation. My patients are happy!
