Mine has two. Its time to upgrade, as it has a mind of its own and refuses to wake me on occation. I would really want one that could do a wake time of at least 4 times. Instead, mine is two, and if I set the two to go off at like midnight and 3, I then have to do a re-set to wake up in the am. does such a beast exist? I guess its that, or do two alarms side by side, and I really dont want to do that. I really want this, becouse when I do the all night testing on matt, it would really help.
