A cell phone stun gun works like other stun guns. You press the end of the stun device into the person and press the trigger. This dumps the electrical charge into their body and overworks their muscle group. The longer you hold it on the person, the more effective the shock effect. Hold in on for several seconds if you can and then get away. You will not feel any shock back even if you are touching the person or if they are holding on to you. The stun effect is localized to where you are holding in on the person.
