I have a really hard time wake up to a conventional alarm clock , regardless of if I get my 8 hour of sleep . I have be late to work and class due to sleep through the alarm or turn it off in my sleep . with the sonic boom alarm clock , I do not even need the sound to wake up . the vibration wake I up right away and the snooze button on the sweetheart version be a little tough to find in the half-asleep stage so I have to be awake to snooze it or turn it off . it be a bit lightweight but for I it serve its purpose . the vibration apparatus just plug into the alarm clock -lrb- leave the option of use it or not -rrb- , and it have a pretty decent size cord -lrb- well , maybe 3-4 ft -rrb- . the beeping option be possible to be a range of different pitch and volume to fit you need , include very loud and high pitch . I highly recommend this product for people who have a hard time wake up to conventional alarm clock .
