In order to measure with our newborn daughter in need, without hassle manner fever I held such a device for the best solution. As the unit has come, I have the pure function checked, so turn and just measure on the forehead and in the ear. That is, it is something appears (to me seemed true 36 ° as a bit too cold, but I was not to worry about it). As after seeding but the situation was serious and my daughter also expressed according quängelnd and was relatively warm and had slightly humid sweaty skin, this device proved to be absolutely useless and nothing to use as it is easy between 1 ° and 2 ° indicates too little. Since it may be in the newborn that the temperature betw. 36.5 ° and 37.5 degrees varies makes a significant difference when the instrument is displaying 37.5 °, but in fact it is 38.5 ° or more. I (already digital) still have a conventional thermometer, this was also used. And lo and behold - my daughter had a fever (have - really - my body temperature also measured - 36.8 °) although the ear Forehead Dingenskirchens yes claiming the opposite. Dear parents ... do not be too lazy to take off your children rompers and open the diaper and just do what needs to be done. It is also only the tip inserted and not half the thermometer, and I promise you, your child will not even notice. But you do not leave on this thing, this is just more expensive scrap.
