If there were a stun-gun equivalent of a "Saturday Night Special," this might well be it. The "Runt" is an economic alternative to larger varieties like the Avurt IM-5, though it doesn't have anything near the fashion sense of the latest Taser line. In fact, it bears a remarkable resemblance to a brick adapter, but don't let that fool you: The 3.25-inch Runt can deliver 350,000 volts for just $40, and $60 will get you a mind- and body-numbing 950,000, according to Coolest-Gadgets. And that's more than enough, as we found out recently, to run afoul of the law while attempting a burglary in England.
