render lost or stolen guns useless

Has anyone put this to the real world test? i.e. Give one of these smart firearms to a few dozen gunsmiths, locksmiths or other curious tinkerers and hardware hackers? Bounty programs?

Anyone here on HN own one of these? How long does it take to disengage the lock if you are the authorized owner?

There was a presentation at DEFCON 25 (2017) by someone who obtained one of the then available smart guns and defeated it with $15 worth of common magnets.

Here's a video of the presentation from YouTube:

I think it was also covered on HN at the time.

Thankyou, I am surprised I missed that talk. That implementation seems rather fragile to me. Assuming everything is working as designed one would have to be wearing the watch ahead of time in a home defense situation. That is also a lot of extra moving parts that could fail especially at the range after going through a few boxes of rounds. thinking thermal issues but maybe they tested that

The gun could run out of batteries is another. The talk goes into two other attacks as well, including denial of service
