Leviton smart lock GFIC

Two outlets gave me trouble in two rooms with different appliances. I
replaced them with new ones of the same brand and they worked great.

I thought GFICs tended to have quality problems which is why you should
test them periodically?

No, it's not Q problems per-se. GFI's have mechanical contactors, and
electronics. The contactors can burn out or stick, and the electronics
can (very occasionally) fry. If it sticks, you have a false sense of
security...

You may have had two marginal units, but from Leviton, I'm surprised.
