Purchased two changed to display Fahrenheit temp accuracy was within specs. Batteries are orbit one can purchase 4LR44 type and pull them apart to get the 4 cells. Humidity has trim solder pads as well, they came close enough as to not need adjustment.

Bought 1/2 dozen. All have readings very close to each other. Put one in frig, freezer and given a few away. Haven't tried they yet in desert heat. Very pleased with them so far.
