I recently picked up a Pilot Plumix as a beater pen to use at
work. After about two weeks of use, my opinion is that this is
tolerable, but not a favorite.

The body is plastic, and feels cheap. It doesn't look bad (not
quite as nice as the Penmanship IMO, but it's visually ok). My
biggest complaint is that the cap squeaks when being screwed on
and off. This has improved a little over the weeks I've had it,
but remains a frustration.

It uses Pilot's proprietary cartridges (or a converter), which
I'm ok with. It appears to have no body openings, so might be
adaptable as an eyedropper. (I'll test this sometime soon).

The nib is nice. It's an italic, around 1mm in physical width.
It writes a decent line. A little dry, but not bad - if not
writing quickly. There's a little line variation, though I'd
be willing sacrifice this if it was a touch wetter.

On the whole, it's acceptable, but I doubt it'll last in my
rotation for long (I'll likely gift it to one of my kids).
