Nothing to say after over a month of regular use. Works great, very little difference with anal thermometer, anyway when there is fever, there is fever! we are not close to some tenths ... by cons, very convenient and not at all intrusive or restrictive for a child. (Mine simply refused the anal thermometer and experience, unconvinced by a decision taken under the arm and in the not very hygienic mouth for me ...) This one allows a single temperature measurement when the child is sleeping without need to wake him, the camera flashes when the direction is bad or wrong decision. Reading is done in seconds and remains reliable over several trials. There has memory the last temperature taken opportunities but personally, I prefer to let the temperature management in my brain rather than a machine, but that's personal ... I recommend
