Anyone use any of these quartz flakes?

I just saw this video on IG. Quartz Flake

Has anyone tried one of these? Especially with the Pockety? I'm wondering what people think of them?

Also known as terp propellers, propeller terp pearls, terp spinner wheels, spinner inserts ...

No I was just posting some of the other names I've heard them called by different makers and sellers over the years, to make it easier to find them (and usage pics and videos of them) online
