Product review (2 stars): Defective?
At first it worked.. then it had problems.  After a while the temperature was not reading correctly.  Then it got stuck on one temperature.  Moved the sensor different places.  Brought the sensor in and warmed it up.  Then the sensor got water in the battery compartment.  Dried it out.  Still not working.  Took the batteries out of the sensor and the thermometer keeps reading a temperature.  What's up with that?

Maybe I just have a defective device.  Don't know.  But I'm attaching a picture.  BTW, it is actually 19 degrees outside, although the sensor is not outside.
