Review on Digital Laser Infrared Thermometer Gun for Kitchen -50°C to 400°C with LCD Display by John Ghattamaraju

Seems accurate enough for my purposes. I bought this to use in my bearded dragon enclosures to control their heating temperature and cool side. The readings make sense when I scan different parts of the case, and the temperature changes in predictable ways depending on how close I'm measuring to the heat. It's easy to use, stable, and turns off automatically so I don't have to worry about wasting batteries. I don't know how to measure the accuracy. So if you want to be perfect, you can do more research. For me a good buy at a good price!
