In the instructions, it says to measure between the eyebrows, we did it... The measurements had a permanent deviation of 1 degree. It shows a higher temperature compared to armpit thermometers, the deviation is always 1 degree higher. Then we tried it on the forehead again, same results, no contact with the child's actual temperature. Potentially dangerous product, as if you rely on its measurements, you would have to give fever medicine to a child who actually has a slight fever. Also, very expensive, if I could, I would return it
