Product review (2 stars): Sensors are not rated for rain exposure!
I wanted to like this unit, but was ultimately disappointed. The sensors were not accurate, reading as much as 2 degrees F different and 5% RH different even after sitting in the same location for four hours to acclimate. The LCD on the main unit had artifacts at first, though these went away after a few minutes. The worst part is that two of the three sensors are not outdoor rated. I didn't see this anywhere in the description. The one outdoor sensor is not rated for direct sun or rain exposure, limiting the installation areas.
