Product review (1 stars): Not cool (pun intended )
I have owned 2 of these from the big box store, and when exposed to the extreme heat of Arizona,  both units failed to the degree of 25+/- degrees off in their readings. AccuWeather.com will say 108, unit says 133. Indoor reading I believe to be slightly more accurate,  but still reads high. Keep in mind I keep both units 6 feet off the ground in the shade. Not cool (pun intended ). Don't waste your funds if you live in the heat. Even when purchased and began use during moderate weather, same issues.
