Product review (3 stars): Humidity displays about 10 units lower than my existing analog monitor, which the analog agrees with my two new DeHumidifiers
Temperature is accurate compared to my existing analog monitor.  My analog monitor totally agrees with my two new DeHumidifier displays, which compare very accurately with the temperature and humidity of my current analog monitor.  Both AcuRites appear to indicate about 10 units lower, e.g., if the DeHumidifiers indicate 45 humidity, the AcuRite(both) indicate 35, the Analog indicates 45.  So I'm a little suspicious of the AcuRite's Humidity Monitor's accuracy.
I have registered both units for warranty coverage.
