Pop the sturdy cuboid clock under your pillow, set its vibrate mode on, and as well as pumping out decibels and flashing a light it will start buzzing and sending vibrations out through the pillow that you are mistakenly clutching in an attempt to shut out the real world.
No escaping that alarm clock. Initially designed for those with hearing impairments, it functions as well for the slug-a-beds, heavy sleepers and those with a habit of ignoring the weaker alarms on smaller clocks.
I guess you’ll jump out of bed in a state of terror and adrenalin, but hey, at least you’ll be awake…
