DavecUK - Thanks. It makes sense. As we don’t know where this grinder is coming from - it’s not Eureka, or Ceado, or Mazzer, or Niche, etc… It’s just some company in china no one has ever heard of (I myself don’t even know who makes this grinder yet, and hence the concerns), specially if they are fitted at the factory. But my question still stands, and it was answered: Looks like the burrs are indeed marked so it would be possible to check it (although one would need to take them off the carriers).
I know there was a rather expensive single dose grinder manufacturer at one point who advertised their grinders shipped with Mazzer Burrs… Until someone checked and they were actually Mazzer clones.
Can’t be too careful these days.
