I just hooked up this unit and tested it. it is built large and heavy enough to wake up someone who is very hard of hearing. it has a large dial and very loud voice to wake you and the vibrator is ample to wake almost anyone. I am very pleased with my initial view of this product.
Love it. So easy to change Alarm times and good looking beside my bed. Will always keep one in my bedroom. This is my 2nd vibrating clock and the first one lasted 15 years.
I am hearing impaired and needed assurance that if a fire would occur I would be able to take corrective action. I am completely deaf without hearing aids.
