Product review (2 stars): Not worth it in the long run
Loved this thermometer for the first 8 months.  We placed the outdoor sensor on a tree in a relatively protected area.  It was very accurate.  However, after winter, it stopped working.  I'm not sure what happened, if it was the cold weather (although we had a relatively mild winter for Michigan), or just it went bad.  Now the outdoor reading for temperature is consistently at least 5 degrees off, sometimes a lot more.  And the outdoor humidity will say 1% when it's raining, lol.  Changing the batteries did not help.  As much as I want to like this product, it is not worth it in the long run.
