Arrive broken, then the ones that aren’t already broken break during installation. If they survived to that point, they will somehow break while in a titanium cage, while all the other ones you have purchase elsewhere have survived for months/years.

Once they break they essentially disappear into dust, so not sure what they want me to mail back to them?
