Driving when you are drunk is not a great idea. You could get into huge trouble and put others in danger. Kisai Intoxicated is a cool watch that has a built-in breathalyzer. It tells you how intoxicated you are. All you have to do is open the sensor cap and press the alcohol button to start the test. Once the sensor has warmed up, blow for 5 seconds, and you are set.
This watch shows you how drunk you are. It also has a game to test your reactions. Just like many other watches, you get time, date, alarm, and LED backlighting. This looks good too!.
