Review on Helect Non-Contact Infrared Thermometer -58°F to 1022°F (-50°C to 550°C), Digital Laser Temperature Gun with LCD Display (NOT for Human) by Eric Rodriguez

Build quality was good and the device looked decent. I installed the battery and tried it on the wall next to the thermostat. The thermometer showed about 9 degrees below normal. I went outside where the temperature was 103 degrees. Pointing the thermometer at the driveway, I expected something hotter than the air temperature, but it was again too low - 96 degrees. I put the pot on the stove and bring the water to a boil. The reading through the water to the bottom of the pot was less than 200 degrees when the water was boiling. I sent the device back and am wondering if the more expensive versions are more accurate.
