The problem with this product is that it is not calibrated. When I first used it, the lowest air conditioning reading in my car was 58 degrees. I happened to read another review that recommended placing the thermometer in a glass of ice water that should be 32 degrees and turning the nut at the bottom of the display to calibrate it to 32 degrees. As soon as I did that, the thermometer read 40 degrees on my air conditioner, which matched a friend's thermometer. It would be good to know in advance that you will need to calibrate the thermometer as it is not supplied. so in a package. Otherwise I like the product and it works perfectly.
