Ketotek Infrared Thermometer: Dual Laser Non Contact Temperature Gun -58-1022℉ with Color LCD, K Type Thermocouple, Humidity - Ideal for Cooking, Pizza Oven, BBQ, Freezer, Industrial Review

This infrared thermometer is practically useless to me as every time I take it out of the truck the battery dies. The device has malfunctioned and discharged the battery when not in use.

It matched my 3D printer's temperature reading, which tells me both were accurate, but I'm sure there are other ways to actually test the accuracy (try this IR thermometer I see), but I'm not a scientist, so I'll have to rely on comparing temperature readings on my own gear until I can someday get official gear.

First, it's much slower in any mode and not nearly as accurate as the $12 orange I got years ago. It has some useless attachments but it needs to be dual beam and more accurate and it's not accurate anymore so $45 BOOOOO. It's terrible value to charge $2 to make a product that sells for $12-15 and then give it more output values with little or no value and charge it $45.
