This is a fairly standard forehead/no-touch thermometer. It is powered by two AAA batteries, which are included. It can be operated in two modes, body and surface. The first is exactly what it sounds like, taking your body temperature. The second is for taking the surface temperature of objects. You can also set it to display degrees Fahrenheit or Degrees Celsius. The main trick that I have found is when taking your body temperature, it is best to aim low on your forehead. The instructions kind of say this, but not explicitly. My only real complaint is about the instruction booklet. It is pretty small and the print is tiny. So, if you are over the age of 40 and your eyes have begun to change so you need reading glasses or progressive lenses, the instruction manual will be a chore to try and read. Just from messing with the buttons on the unit, I can tell that there are some other settings/features, but I am not in a big hurry to try to read through the instructions to figure them out. But, if you want it just for taking your temperature, without the need for sticking a thermometer in your mouth, this is a good option.
