I find it works well when my intent is clear. For example, I might want to log a value I just computed for debugging purposes. I type LOG, wait a second, and it completes a zephyr logging macro, complete with a sensible message and the value I just computed.

It sort of feels like pair programming with an undergraduate, except copilot never learns. That isn't to say it's bad, more that it is just a tool you can hand simple stuff off to, except the handoff is zero-effort.

EDIT: I will say that there are times when it makes up fantasy constants or variable names, that seem plausible but don't exist. An eventual version of Copilot that includes more normal autocompletion information, so it only suggests symbols that exist, will be a stronger tool.
