These strikes every 2-4 measurement completely fail with an error message. Also, the measurement at one and the same place just a few seconds later, shows already at differences of up to one degree. Is like playing the lottery: pure chance and luck if you get really times the actual temperature.
In addition, the display without lighting is almost indecipherable. And which is on only when a new measurement. If one wants to look at the memory you have problems.
A big letdown.
