It's fine, no worries. It holds really well. It was in an air conditioned room, now it's in the basement. It held great in both locations. The digital readout was perfectly calibrated too, I checked it against 3 calibrated thermometers. It also has a temp alarm, it sounds (and is very loud) if the temp goes too high or low for a certain period of time.The nurture right you were mentioning... sorry I wasn't clear.
