Even Ninjas need their sleep. For a Ninja, sleep is a time of renewal, contemplation, and rejuvenation. And when a Ninja sleeps, it is a very deep sleep. Most sleeping Ninjas can only be roused from slumber by another Ninja, which is a big problem if you are a Ninja, are tired, must wake up for a secret Ninja mission, and the only Ninja in your office. Good thing we found the Sonic Bomb Clock - it will wake even the soundest Ninja Nap.
The Sonic Bomb Clock has an adjustable volume alarm with a maximum loudness of 113 decibels (just for reference, a jackhammer is about 100 decibels!) And the bed shaker does just that. Slip it under your mattress and your ears will bleed and your bed will shake, and there is no way you will oversleep. Or, you could turn the sound alarm off and tape the bed shaker to your office chair. You'll be vibrated awake without disturbing the drones. Then you can get back to your Ninja activity refreshed and ready for action.
