This thermometer works in 1 second. It has a silent setting which doesn't wake up baby in the middle of the night. I have a baby and a toddler and I can use one thermometer for both of their ages as the usual ear thermometers can't be used on babies under 6 months. This one can be used by babies on the forehead. It's small, compact and has a lovely carry pouch which makes it easy to store in my baby bag. A big bonus is that the package comes with batteries so you are ready and set to use it straight away. After spending so much money on thermometers which take way too long to get a reading with impatient children, this Ritalia forehead and ear infrared digital thermometer is the best. I advise every new parent to own one of these. It makes life so much easier in stressful situations when your little one is unwell. Absolute 10/10 product. Love it. Quality without the expensive price tag.
