How effective is a stun gun?

A stun gun is an effective tool because it can help distract an attacker when it is used for self-defense. In some cases, it can even temporarily disable them, giving you more time to get away and find help. 

When the stun feature of the tool is activated, it sends out a high-voltage electrical current. If the current makes contact with a person it is not only painful, but a literal shock to their body. 

It's important to remember that if an assailant is under the effect of drugs or alcohol, this can reduce how well a stun gun works on them. But, the loud zapping sound it makes can sometimes be enough to scare them off without contact.
