Product review (1 stars): 2 months and outdoor sensor fail
I bought this to replace a larger AcuRite I'd had for 5+ years (that units outdoor sensor failed.  This new one was ok for about 2 months (thought inside temps conflicted with AC thermostat.  Now the outside unit is reading temp and humidity incorrectly; despite careful (shielded from the weather) placement of the transmitter sensor.

Time to hunt down another brand.
