We have them at work....ours are made by Taser International. Those things are awesome. I've actually seen people shit themselves because they've been tased...its pretty funny. BTW, the ones we have can be used as both a taser and a stun gun. If you have the cartridge with the probes in it loaded into the taser, they will fire as projectiles, but if the cartridge is not in there, there are just two electrodes with the current arching between them, and it can be used as a stun gun. Those things are the best toys my job has ever gotten.
