NEWS – The Streetwise Sting Ring is a rechargeable “stun gun” that you wear like a set of brass knuckles. It might look unassuming, but according to the Streetwise website, this little self-defense weapon will deliver an 18 million volt / 0.85 micro coulomb / 2.5 amp zap when you touch an assailant with it! That sounds like a lot, but it’s non-lethal. The Sting Ring features an on/off switch that you can activate with your thumb and then to deliver the zap, you just squeeze it in your hand which presses the main button with your palm. Check out the video below which shows it in action. The Sting Ring is only $18.95 from thehomesecuritysuperstore.com. Just make sure you check the laws in your state before ordering one.
