It claims to be a useful tool for pen testing. I call bullshit. Destroying a device is hardly the same as penetrating a device. Does this have a legitimate use case?
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.
Aww, you don't sound like a fun-loving kinda guy :-/
