If you are someone who has trouble waking up in the morning, then this is the perfect alarm clock for you.  Because when this alarm goes off  you won't just hear a loud siren, but also flashing lights and even some bed-shaking action.

The palm-sized vibrating bedshaker unit is powerful enough to shake your bed and you can select from a combination of bed-shaking, flashing lights  or loud pulsating alarms for your wakeup alarm. The clock also has a battery backup and can connect with other signalling devices like smoke detectors, door bells and even telephones. Available for US $54 from here.
