I've got the 5028 set in silver-white. Like a previous poster said, it feels cheap -- very light in the hand and a slim section. On the other hand, it *is* cheap....
It performs well for me. I started with the 1.5mm nib, and I'm using the 1.1mm nib now. Both nibs have been reliable -- haven't touched the 1.9mm nib yet. I've used two Noodler's inks in it without any problems: X-Feather and Bad Blue Heron. The converter is a slide-type, nothing fancy.
Eventually, I'll probably get a LAMY Joy with 1.1mm nib, but the Hero 5028 has been a fun way to get acquainted with italic nibs.
We shall this day light such a candle, by God's grace, as I trust shall never be put out!
