Product review (4 stars): 2.5 years of use
I bought mine in Jan 2015 and It just stopped working.  Apparently the alkaline batteries had moisture condense on them and it corroded the terminal in the sensor.  Still two and a half years is not bad for an outside mounted sensor.  Mine was mounted on the inside of our porch post about 50 feet from the reader station.  I'd like to upgrade to one that also gives barometer readings.
