Query: Started acting weird after nearly 3 years, going to replace it.

Amazon says I purchased this on October 28, 2009. Worked good since then.This morning, 7/20/2012, it went off at 7 AM and I peeked at it. I closed my eyes and continued to listen to the radio while I woke up. Then it just stopped!! It's never done that before! It would stay on for hours, usually! I peeked at it again... 7:08 AM. Okay, so I have to try to get myself up. I started wiggling my toes so I wouldn't go back to sleep. I peeked at it again: 8 AM. Now, I *KNOW* I did not drift back to sleep, because I would have stopped wiggling my toes and I never broke the motion. I checked the time with my computers and the clock was way off.The bottom line is that when this ticker starts to malfunction, you're going to miss appointments.
