Jinhao, Hero or Baoer rollerball refills an alternative to Schneider or Schmidt eurosize refills?

[mr T.]

I use a Waterman Apostrophe rollerball with a Schneider Topball 850 eurosize refill. Sites like AliExpress offer quite a lot of refills that are sold as Jinhao, Baoer or Hero refills for what seems to be very low prices (even with shipping from China). Is it possible to use these refills in eurosize rollerball of a Waterman rollerball? Are refills from Jinhao, Hero or Baoer (in general) good value compared to eurosize refills from Schneider or Schmidt? What are your opinions about these Chinese refills?
