Product review (2 stars): The indoor thermometer part works fine and agrees with my other house thermometers
The indoor thermometer part works fine and agrees with my other house thermometers, but the outdoor sensor seems to be reading consistently 4 or 5 degrees too high. I had both units next to each other indoors overnight, and the indoor part read 69 degrees while the outdoor one read 75 degrees. Followed instructions in sheet to a T; took batteries out and repeated.
