The One Million Volt Stun Gun with Flashlight and Red Laser is an advanced stun gun with the latest research behind it. This unit is constructed of durable aircraft aluminum. What makes this unit so unique for self-defense is two features. The first feature being the spikes at the end of the unit. The second feature is the red laser mounted on the unit. Why would a red laser be mounted to the unit? The reason being is that our eyes and mind recognize the color very quickly in high stress situations. In a self-defense situation, adrenaline has been dumped into the bloodstream, your focus is on the attacker. When that red laser is on the attacker. You will instinctively drive the the unit into the attacker and press the button to engage the stun, disabling your attacker. The flashlight option of the unit features a strobe option (move the swich up and down twice to engage) and a steady light stream. The unit is rechargeable and comes with charging cord.
