Seems just a little irresponsible to not have a warning printed on the outside of a device that looks largely like a flash drive. Even better: a physical safety interlock; something like a red button with a shield. In its shipping state, it's a hazard to anyone not the original buyer who happens to come into possession of the device after purchase.
