Personally, I don’t think I want to hold one side of that little plastic piece of crap in each hand while energized when I remake the ballast connection. Especially not under any load and even more so with 277v.

That's exactly the first thing that I thought of when I saw these devices for the first time. I'm not even crazy about the little connectors that plug into the backs of smoke detectors. The NEC is a great reference to ensure suitable quality and uniform standards. Sadly, it's become nothing more than a manufacturer's marketplace as they waste our time continually reinventing the wheel every three to six years.
