Review on Accurate Non-Contact Infrared Thermometer for Adults - Forehead Thermometer (Purple) by Crystal Velar

A later. Advantages: Nice size and pleasant feel. It seems to do exactly what is intended. Only used three (3) days. Accuracy not compared to calibrated block. Fairly consistent, subjective values obtained. Keep in mind that it would be unusual to always get the same results whether healthy or ill. Fluctuations +/- 1 degree should not worry. Throughout the week, take notes each time you use the thermometer to understand your personal, normal deviations. Temperature changes are just one indicator that needs to be used in conjunction with several other different indicators to be a valuable medical indicator. Take care. Stay fit. Live long and prosper ! ; )B. Cons: Maybe I missed something in the manual for the device. I've used the device several times and the results have changed, but not by more than a few tenths (0.1). Then the results for me and the other person were consistent and identical. After a bit of research and observation, I noticed that the letter "M" was showing up on the screen at this point. Again, if no "M” was displayed on the screen prior to using the device, the results between me and the other person consistently differed by no more than two-tenths. I believe that the letter "M" should not appear on the screen before using the device to get reliable readings.
