Review on ACEGMET Handheld Waterproof Durability Infrared by Shigg Bigbee

Mine freezes every few seconds. After a short break it works again. If it works, it's great. The ability to highlight hot and cold spots comes in handy. I've used it to troubleshoot HVAC output issues, detect overheating components on PCBs, and identify which devices aren't cooling properly. It was very helpful, so much so that I'm only deducting one star for the annoying pauses.
