The small size of a mini stun gun does not draw attention, and in fact, people probably think the mini stun gun is some sort of personal item or electronic device such as a portable game player or an mp3 player.

A mini stun gun is about the size of an ordinary cell phone. One of the most popular mini stun gun is the pen stun gun.

A mini stun gun is quite possibly the single most effective non lethal self defense stun gun weapon available on the market. Often, just a test fire of a powerful self-defense mini stun gun into the air is enough to scare off attackers. If the sight and sound of a mini stun gun doesn't stop the attacker, then surely the act of zapping the attacker will!
