Product bought it a few months ago but not used until then. So I tested when my son was sick (flu among others). The thermometer reads 36 ° 5 am when he has more than 40 ° with my basic thermometer. In addition, despite several taken on the forehead and ear did not indicate to me 2 times daffilés the same temperature. In view of the price I thought it would be reliable, but then not at all, so I resume my basic electronic thermometer.
