Product review (1 stars): The indoor readings are accurate, but not the outdoor readings
The humidity reading was anywhere between 10-60% off, and also the outside temperature reading has been stuck at 68 degrees for a few days.  (It is currently 43 degrees outside!)  Also, the main console has to be place with absolutely no obstructions between it and the remote sensor, so we had to place the sensor in a very obvious place on the deck, unlike other brands of outdoor thermometers.  Had this for a week and am returning it today.
