    These are NOT good electrical conductors. The mating surfaces are coated with a very thin layer of some sort of clear polymer; it’s what allows them to spin with little friction. You can sand off the coating, or try to scrape it off, and as it gets worn away, it will provide an intermittent connection. It can be made decently reliable with enough careful sanding.

No public wish lists :(
