That’s what I thought too when I saw this on GadgetVenue. But it’s legit, and on sale for $30 at Defensive Devices. These are actually rechargeable and includes an integrated flashlight and safety pin (in case, I guess, if you forget what it’s for and try to do a quick touch-up). It purports 350,000 volts, though it doesn’t state for how long that voltage lasts.
