I think many don't appreciate just how horrifically cheap and dangerous some of this stuff is. Not just vapes, but things like charging bricks too.

I'm generally not a proponent of draconian regulation but I firmly believe that any electronics handling substantial voltage not approved by UL or similar should be rejected at the border. It's all dangerous and incentive to manufacture it needs to be curbed.

I have seen things approved by those sort of organizations that were extremely dangerous, such as a listed fire alarm that when installed has a significant chance of becoming silently deactivated.

With that said, it can be even worse when it isn't listed.
