Query: Dud?

It doesn't seem like most people got a dud like I did. I got ONE temperature reading out of it, and that was it. It no longer cooperated. It would turn on, but would not make any reading. It still has it battery in it unfortunately and turns itself on for no apparent reason. I've had it for three months, and it still continues to turn on/off on its own.
