Review on SIMOEFFI Non-Contact Digital Infrared Thermometer - Dual IR Laser Thermometer for Cooking, Kitchen, BBQ, Automotive, Industrial Use - Touchless Temperature Gun (-58℉~1202℉ / -50℃~650℃) - NOT for Human by Ken Kowal

Very easy to use. There are some more advanced modes of operation that most people will probably never use (like finding the area of a wall). Otherwise it's easy to use, just point the laser and read the temperature. The measuring range is not small. It averages the temperature over a range that increases with range, so I don't think you can measure the temperature of a component on a circuit board, for example. To check the calibration I measured the temperature of the ice water at +/- 0.2. Grade C, so pretty good. All in all a handy device and a very good price-performance ratio.
