I'm not going to buy it, but I think it's an interesting idea.
Anyone know what they're made of?
If it's heavy enough, and if it's moving fast enough sdo that it gets decent penetration, it might actually be useful.
If the cable actually stays attached, it could potentially be a pretty devastating round against soft tissue.
But that's a whole lot of "ifs".
I'll definitely keep an eye out for gel tests.
It might not be nearly as useful as a new JHP design, but - whether it surprises with success, or amuses with dismal failure - it should certainly be more fun to watch than yet another picture of ~14" of penetration, and ~1.5x expansion.
