I use the thermoscan braun for 4 years and I am delighted. Well initially I was a little disturbed by its operation and more ^^ first baby so I always checked the classic rectal thermometer ^^ but to use force I have had to go to the obvious: yes it worked perfectly and no need to verify rectal ^^ with this thermometer can measure the temperature every fifteen minutes if we feel like it to check if the temperature goes up or down and this without waking baby! by cons we have to think about buying at the same time reserves ferrules, even if I do not change with each shot, I change it anyway to everyone because it is also used for us parents, still more pleasant than getting a rectal ^^ and so much faster! to verify that it works well and calibrating, take its temperature when it is not ill to have a starting point for each person (eg my son normally not sick. 36.6 °) in 4 years we changed Once the batteries and yet in winter, it is never stored because it has always needed. Here, I am delighted and recommend it to any parent anguished by the temperature of her sick children!
