Yeah from start to finish these guys are just so obviously full of crap that its pretty funny.
Honestly though, that thing doesn't look like any resistor I've ever seen. On the other image from the site selling the thing, its translucent and you can see the wire inside, that looks far more like a non-standard SMD fuse than anything else.
The outer C section is just probably SS, that inner hunk of metal clamped around the rice pins looks like cut pieces of a bare, surface mount sense resistor to limit current since a typical fuse has a resistance far too low to fire on its own and the chip is likely nothing more than a high melting temperature fuse of some sort. Why else have such a poor attachment method for the
"chip"?
In short it looks like a high melting point fuse (a nice fuse at that) with pieces of bare resistor put in series to limit the current.
Its clever, but nothing special and most certainly not Silicone Valley material. Only the true manufacturer knows what the hell the material is and I have serious doubts that the kid working out of his parents living room has the faintest clue.
It'll work for a while, but there's just no way all those press fit connections are going to last. We're talking 8 press fit connection points using 4 different materials from base to chip that will expand and contract differently. A traditional device only has two connection points and two materials, the SS of the screw/base and the wire.
Now I've barely even touched on most of the absolute BS in the description of the product, the presentation, or the people behind it. There's no need. Only a fool would fall for it....
...lucky for them there are probably enough fools for them to earn a good living.
