My wife purchased this for me because I get up early in the morning to workout, and the 5 AM alarm clock was waking her up. The neat feature that attracted her to this product was the vibrating alarm on it. For me, that meant wearing it to bed at night and hope/pray that it wakes me up at 5 AM.

If I were a hunter or liked fishing in the wee early hours, this would be an awesome watch to use. You plug in your longitude/latitude, whether you are daylight savings time, and presto! it automatically is configured for the ideal hunting/fishing times. Not being a hunter or stream fisherman, I didn't realize that there were ideal times, so I better watch those shows on PBS a little more closely next time. It also has a nightlight feature, so that if you tilt the watch towards you, it lights up, tilt it away and the light goes off. That prevents disturbing the fish or wildlife. Doesn't that make you want to go hunting/fishing with your buds?! So Cool!!

But I digress. Back to the real reason for using. All I can say is if you go to bed late or are a deep sleeper - forget about using this. Secondly, if your wife is a light sleeper & goes to bed late, then it's not going to work for her, either. The vibrating alarm is very cool, but it only lasts 10 seconds. However, since its a hunting/fishing watch, it has multiple alarms (I think up to 10 times can be set). SO I set up the alarms to go off for 10 seconds every minute up to 10 minutes. I usually get out of bed on the second or third iteration. A few times, I left the watch in my bag with the vibrating alarm on and it woke me up because I could hear the thing vibrating in my gym bag.

Bottom line is that its worth a shot using this, but make sure that you go to bed early (get enough sleep) in order to feel the vibration on your wrist. Don't expect it to completely cure your early morning wakeup problems as my wife still wakes up, whether she heard the vibrating alarm or heard me tip toe across creaking floorboards or squeaky door hinges, etc. Another note - it took me a while to figure out how to set it up correctly, and the manual that came with it was a little confusing, too.
