Review on Etekcity 749 Infrared Thermometer - Non-Contact Digital Temperature Gun with 🌡️ LCD Display (-58℉ to 716℉), Ideal for Industrial and Home Use (Black-Yellow) by Marc Hawkins

The voltage detection function is practically useless and only confirms the presence of voltage but does not report the voltage to the user in the form of readings. The device needs to be within inches of power to even know it's there. Temperatures aren't much better. I wish I had never bought this one. A simple single beam function to measure temperature would be much better and cheaper. Accuracy is difficult to determine. This value changes every time I measure an area for a few seconds, even though the area's conditions don't seem to change at all. I will buy another device that better suits my needs.
