Works great. Feels like you wake up 5 minutes before it goes off!
Throughout my entire life I have never been able to wake to my alarm, happily that is.<br /><br />The first few nights of this watch.. were difficult. I have found, by using this watch, that I go into long periods of deep sleep. I simply set a larger window (60 minutes) for this watch to wake me up. I was thinking that maybe this would make me feel that I was loosing sleep every night, it was in fact...the opposite.<br /><br />I was a bit skeptical at first. To my surprise this watch worked amazingly well. I highly recommend messing around with the awake window, and setting an alarm clock to go off at your required time (just in case) for the first few nights.
