I've seen a plumber use it to document a repair that he was doing. Being able to record in tight spaces seems to be a good use case for this tech

I've also seen a home inspector use them to document issues with a new construction

There's also a ton of people using it for cooking videos

The only real usage I've seen is on Instagram reels etc. where people are using them in red light districts like in Amsterdam to film the women.

I have them and like them. I don't wear them constantly, but on days when I'm doing something interesting, they help me document much more than I otherwise would.
