It's because people vary that I believe posting a variety of links is useful.

The ones you posted are an interesting idea - certainly it's straightforward enough to program one of these gadgets to give you a zap if you visit the 'wrong' website. But how to link that effectively with breaking certain trading habits?

The BBC video shows it software controlled but it has a button you can just press, presumably there is a delay.

Someone's review described just pressing it when they looked at refined sugar for example. The limbic system (amygdala etc.) is most would agree from my own research, not under significant/any conscious control. You can't talk to it, it learns by it's own experience.. a passenger sharing the senses.

But it would only work for a % and maybe half the reviews are kickstarter funders Possibly a connector for over trading, moving stops, failure to enter a position on valid signal if suffering from 'The Fear'?

I am presuming the shock is more distressing than a rubber band of course
