I am extremely disappointed. I wanted a slightly Hi tech thermometer for my daughter. History can take her temperature without bothering (parents will understand). I chose this one because it was on sale flash one day. I read the description he had been tested in a pediatric emergency department. In short, I plug it and try to take my temperature. The thermometer reads 32 ° me. I take the t ° of the room, 33 ° (there is a function for this purpose). I let you imagine the t ° of my body was not 32 ° and that of the room either. Anyway, I just hope the tests to emergencies were more conclusive.
