Excellent product from FNIRSI, Quality and design are well done. I have an old version of Geiger counter but here it integrates Nuclear Radiation and EM radiation detection. Could not find any other product in the market integrating both and with this quality design. Comparing the radiation of my old device and FNIRSI average value is 56% Lower than my old device. Not sure which one can be relied on. Real time value does not show a big difference, the difference seems to be in averaging the values. The package arrived without much delay.
