After a video about the perfect cooking of steaks ('Eat right - Alexander Herrmann') I had no idea how hot the frying pan because now is when I put the plate to a value. With this thermometer that was easy and as part of the application in my view, sufficiently accurate. Knowledge: a position to "4" - "5" is sufficient to a steak at max. Frying 140 degrees - which I did not think. Good - a look at the manual would have possibly can tell, but it is practically determined value. The use of the thermometer is simple and "succeed" each: press button, keep laser spot on "Points of Interest", wait moment. After releasing the button, it will beep and the temperature value is shown on the display.
