I've been using Parker pens since high school 2nd year (more than a decade ago), for rollerball I mainly had Vectors and it wrote fine enough although being a rollerball the refill lasted me 6 months max.
I can't recall if those were the F 0,5mm refills but I suppose not as these feel a bit 'finer' on the paper than I can remember that well enough being in the past.
As this is a Parker proprietary refill, it will work in any Parker rollerball. I'm currently using a Parker IM as it looks classy AF.
