It's a tool! It reads the percentage of alcohol. I found it easy to set up and use and the instructions are in good English which is a lot! My first reading of the 80 proof bottle showed 38 percent after calibrating it. It should have been 40 but there must have been some evaporation because it was an old bottle left open during the party. I am very happy with it. You can catch those pesky kids adding water to your alcohol stash. LAUGH OUT LOUD
