Product review (4 stars): Review Update: Pretty Accurate 
July 2016 Update:  After my review in 2013 I put both of these units in a storage box. After moving to Arizona I decided to compare the two monitors to a newly installed thermostat & indoor/outdoor thermometer. To my surprise the temperature and humidity readings on both monitors were pretty close. I'm satisfied!

2013 Review: Purchased 2 monitors and expected some degree of accuracy, especially regarding the Humidity feature. The Temperature feature was pretty accurate, however, the Humidity feature was off by 10-15% - not acceptable. The comparision was between a humidifer, a wall display and the Vicks monitors. I would not recommend purchasing this monitor.
