How do you hear it, or is it flashing lights. Silent alarm ?
Vibration isn't silent you hear (just barely unless it's laying on a hard surface) and feel the vibration. Vibration alarm. :winktongue:
Silent alarm makes it vibrate at the time you set. The "silent" part is referring to the fact that there isn't a loud alarm, just the vibration. It is a nice way to wake up in my opinion, and I prefer it to my phone alarm.
