Doesn’t seem any more effective than pepper spray or a taser. Well maybe if you shoot them in the face or the nuts…but other than that, it doesn’t look powerful enough to really be debilitating.

In states that require one, you’d need a concealed carry permit as well.

Also, that is one thick credit card.
