Looks like a good way to separate the masses from some dough... it may do something like what's advertised, but anyone who shows up with a miracle cure has a pretty rough job convincing me that the cure is worth the cost.
$100 bucks plus shipping for a chunk of machined brass is a headscratcher for me -but then, I'm notoriously cheap, and until I ordered my Warmoth goods recently, had never paid more than about $550 for an entire guitar.
