Yellow Jacket has created an iPhone case that doubles as a stun gun. According to a promo video for the product, you may use this to avoid: robbery, assault, rape and murder.
Sounds like a solid idea.
"Here at Yellow Jacket, we know from first-hand experience what is needed in a violent situation to escape danger," the company says on its site. "We have designed our iPhone 4 stun gun case to be easily deployable with one hand. In less than two seconds, both safety mechanisms can be deactivated and the Yellow Jacket stun gun is ready for action. Compare this to a regular stun gun which can take five to ten seconds to find and deploy."
"Our iPhone stun gun case is capable of stopping an aggressive attacker," Yellow Jacket says. "The 650K volt of electricity flows from the electrodes and into the assailant upon contact providing a potential victim with the opportunity to escape danger. Unlike other phone cases, the Yellow Jacket iPhone 4 case gives you the ability to defend yourself."
"The effects of Yellow Jacket are loud, painful and disorienting," says co-founder Seth Froom. "We developed the Yellow Jacket to be able to take down a fully grown, aggressive, adult male."
For now, it's just available for the iPhone 4 and 4S, but Android versions are on the way.
