First of all, I must say that you shouldn't believe the claims that this alarm clock has a battery back up feature, as my power has gone out several times and it has never worked. Also, I have yet to find a button on this thing that will actually turn the alarm feature OFF. Which means that someone like myself, who works a rotating schedule, must always remember to reset the alarm to a later time or else wake up at the crack of dawn on their day off. There are so many buttons on the top of this alarm clock that it's very difficult to hit the actual snooze button when you're half asleep. Don't waste your money on this one!
