I already own a couple HF IR thermometers, and they have been very useful, far beyond their low price.
I just picked up another one, a newer model (item 60725).
I find it to be a much improved tool, at the same price.
Better interface, easier to use, more stable readings, better repeatability.
As with any IR device that has a laser pointer incorporated, the device does not measure the temp of the dot-area, rather it measures the average temp of the area of a circle of a cone with the dot approx in the center.
All in all, I find this device to be an improvement over previous HF IR measurement tools I have owned.
Best,
