I've been using this pen for a while, not sure how long with the hero 234 ink. It's perfect. The nib and the pen itself still has the old moonman branding.
My workhorse pens are my three pocket pens: an Ensso XS Pocket Pen, Kaweco Brass Sport, and a Big Idea Design EDC Fountain Pen. I keep a pocket pen and a regular sized pen inked at all times, but I tend to rely more on the pocket pens since they are easier to carry around.
I really got my money's worth out of a Muji fountain pen, but now I've been sticking to my Diplomat Aero in Black Stripes with an EF nib. Love the combination of anodization and raw aluminum in the hand!
