I have only ever been able to get accurate readings on this thermometer once. The rest of the time the readings tend to be on the low side and can fluctuate by a number of degrees from readings taken within seconds of each other. It is hard to even get a ballpark estimate of what the temperature might be in these instances. I have tried using it with the probe covers as recommended and in desperation tried it without the covers. I still got inaccurate readings. I would spend my money on something else.
