Best thing about this thermometer, speed and simplicity of measurement: in the second, the front temperature or atrial appears. For this reason, it is particularly intended for small children or infants that bite crisis at the rectal temperature taken. Further measurements can be stored, useful to monitor a fever before going to consult. Be careful with temperature deviations from a rectal thermometer ... leaflet specifies the clairement.On can also noncontact measuring any element of surface temperature (I do it for my aquarium temperature!). Now lets disadvantages: without a total complexity, there still has many buttons and settings, so that in the context of a very occasional use, it will always return to record ... annoying! So all is not very intuitive. Also the location of the buttons below and the device is not ergonomic when it comes to press them simultaneously (for a setting change, for example). A reservation for a particular purpose therefore.
