The measurements are completely wrong, I have never seen it on a thermometer before.
With other thermometers, it measures 37.8 while with this one it's 36.9.
It has not shown correctly in any use.
Very fast indeed and that's why I bought it, so as not to bother the baby, but it's really useless.

I saw the first 2 good reviews it had then and I also bought it because I wanted to have a quick measurement and not bother our baby while having a fever.
For babies, it is terribly inaccurate, the child had 37.2 with a mercury thermometer and this one showed 36.6, which is a big difference.
For adults, it plays within +/- 0.2 like most thermometers.
It is incredibly fast, but what can I do if I wonder every time what the real measurement is, especially for a baby or child
