Product review (3 stars): The outdoor sending unit for this Acurite thermometer stopped working ...
The outdoor sending unit for this Acurite thermometer stopped working today, after being in use for only 7 weeks.  This unit replaced a Radio Shack model which finally failed after being in constant use for over 25 years without a problem.  I will be contacting Acurite to see if their 1-year warranty protection is valid,

Update - February 21, 2018:  Apparently this unit takes longer to synchronize than I had realized!  Several hours after replacing batteries in the outside sending unit, it came back to life and has been operating just fine now, over 24 hours after I discovered it had quit.  As an electronics engineer, it did not seem reasonable to me for this device to take so long to re-synchronize with the receiving unit, but apparently I was wrong.
