Review on 🌡️ PerfectPrime TM0300: Accurate Non-contact Infrared Thermometer Laser Pointer Gun -58~1112°F by Sean Copeland

Does not work. First, it was foolishly inconvenient to open to insert the battery. Second, it reads the temperature incorrectly. When I finally put the battery in it said my countertop is minus 10 degrees and I found that very strange so I tried it on my forehead and my sisters forehead and it rejected at least 15 degrees for all of us. So I tried again on my 78 degree tank and it said minus 10 again. I did a hidden calibration but that didn't work either. It says my leg is now 473 degrees as shown in the picture.
