Product review (1 stars): Drifting Inaccuracy
The temperature read out constantly "drifts" to an inaccurate reading after 1-2 days of use.  Having used the product for approximately two weeks now have consistently had the problem of inaccurate temperature readings.  The base unit is next to a thermometer and the outside unit is hanging from an outdoor thermometer.  When the batteries are first installed both units registered the correct temperature, but the next morning both the inside and outside readings were about 9 degrees different than the thermometers they were near.  I took the batteries out of both units and then placed them back inside the units.  After putting the batteries back in the temperature reading for both outside and inside then snapped immediately back to the same readings as the thermometers.  This same pattern has now continued for the last two weeks with the temperatures not matching the thermometers, but then matching again after removing the batteries and then re-inserting them.  Mainly bought the unit for the humidity readings so with the constant problems with the temperature readings hard to know if the humidity readings are accurate at all.
