I don't think the OP is "promoting" this, the BioShield Key has been all over the news, and I hadn't even thought to look at the products' site till now.
No one here is going to buy this thing, the point is to foster a conversation about it. I'm not entirely convinced this isn't going to turn out to be ironic or some viral marketing tactic.
Perhaps it is time for HN to start permabanning people who promote this sort of garbage.
