Product review (1 stars): Not accurate for AcuRite indoor/outdoor wireless thermometer
As other reviews have mentioned, this was very easy to set up.  And I found it to be the most attractive of all the available brands/models on the market.  However, the outdoor humidity readings were often very inaccurate.  But more surprising was that within a few months of owning it, it would only show 158 degrees as the outdoor temperature, and 1 degree as the outdoor humidity, but the indoor temperature and humidity worked fine.  Then somehow it reset itself and kept working.  But then after about 15 months, the whole display went dead.  The battery was fine, and I checked all the troubleshooting items in the directions.  After that, the display did return, but only to again show the 158 degrees outdoor temp and 1 degree outdoor humidity, as it had done before, with the indoor readings staying accurate.  So I would definitely recommend against getting this thermometer.
