I friggin love this alarm. Ive got the barcodes set to my coffee can, a bottle of Baileys, and my shampoo so I dont forget to shower.
A word of caution: disable the "type in the barcode to shut off" feature, and make sure that your phone/iPod is NOT on silent mode. The alarm works like every notification (except your regular alarm) in that if the alarm goes off and your phone is on silent, it will just vibrate. Disabling the type in barcode thing will keep you from mashing numbers until you get it right and pass right out again.
I recommend setting your phone alarm about 5 minutes before the barcode alarm to help wake you up, and then setting several barcode alarms to keep you moving.
Also, let your phone charge on the other side of the room, preferably hooked into a stereo set to max so you wake up like you just got shot at.
