STUN MASTER® has been a leading brand in the stun gun industry since 1994. This type of stun gun does not rely on pain for results. High voltage and low amperage temporarily disable an attacker for several minutes. The energy stored in the gun is dumped into the attacker's muscles causing the attacker to drop to the ground with strong muscle contractions allowing you to get away. STUN MASTER® comes in a variety of affordable models.
