There are people due to body mass or being high on drugs that will not be affected as easily, and that may be the reason you would want a higher voltage device.
You should carry of keep the device where you can get it quickly, and you should be familiar with the safety device that keeps it from discharging accidentally. When you use the device touch the first part of the person's body or clothing you can reach, and don't aim for a particular spot. Squeeze or push the trigger for 3 to 5 seconds and if the attacked doesn't fall down, do it again. As soon as the attacker is disabled, run, don't hang around. This is a defensive weapon designed to give you time to escape or seek help.
