For device:
The Gärät fits comfortably in your hand and is very light. The display is a good size, you can read the numbers well. You can choose between ° C or F select, display illuminated or not, laser beam for aiming on or off. As with a gun to solve the temperature measurement via lever pressure with the index finger.
5% deduction gets the device, as it displays different temperatures, the closer you get the heat source. I do not mean to compare 20m to 2m. When I measure the outer wall of my kettle of 1m distance and then by 20cm, is there already a not so small temperature difference. For those who want to have very precise measurements, may want to purchase a much more expensive device. For those who need benchmarks - like me, it is optimal. I imagine that my floor values are displayed well, and if all are equally good / bad display, then I still have a benchmark, which I can compare what.
So from me a clear Kaufentfehlung
