The device is easy to use. However, the calibration needs to be done multiple times (comparison made with a conventional thermometer). And each time, the correction factor is different. Once a correction value determined and saved, the camera does not take into account and gives the temperature measured without correction. After multiple attempts and rereading the instruction manual, nothing happens, we are, each time, to more of a degree of reality, with some variability. If we compare each time with a conventional thermometer to be sure, there is no interest. I hoped, taking a renowned brand apparatus and significant price advantage of a reliable device ... The product is likely to be returned ...
