Query: Super Sonic Boom (Very Very Annoying)

Unless you want everyone in the house waking up with your alarm, don't buy this thing. The SUPER SONIC boom vibrations are capable of shaking up a whole house. I returned it just after 2 or 3 tests right after I received it. May be some people need this to wake them up, Not Me!!!
