Well I will say "Keystone recalls all models" got my attention.
But the link John provided answered my questions.
Though I never used it and didn't even know of it's existence, it is/was kind of reassuring that Keystone would provide such a link. And it is equally kind of disturbing that they would remove that link to information.
Oh well, just another day in the year of weird. 2020 I will not think back to you fondly.
