This "gun" is very convenient. It measures the surface temperature of objects without touching them. It is very well finished and was especially well in hand. A small screen to instantly see the result. It is written large, so I did not even need to put my glasses. One can choose the unit of measurement (Celsius or Fahrenheit) through a small button. One can backlighting the screen, with a second, and the third button enables or not the laser sight. The three buttons are located just below the display, and manipulate very easily a boost. A 9V battery is provided, remains just unpack and connect the device to use. The instruction is in English, but frankly, the use is so intuitive that it is useless.
I use it mainly for measuring the temperature of the water in my pool, it works great, it's instant and I did not even need to bend down. I also tested cooking is very convenient. In short, a good acquisition I recommend.
