Great refill. Definitely a finer point than the medium point my pen initially came with. Bought it to use with 5mm graph paper and it's perfect. Thumbs up!

Good smoothness so far. I have used the blue ink in fine point and happy with it. I also use the black medium point refill in several of my compatible Non-Fisher pens. They give a small plastic adapter for the refill so that I can put it in my Parker pen. I sometimes write with pen pointing tip down but usually I'm writing upside down and this refill allows it. My other regular, gravity-operated pens can't do this ! I'm satisfied so far...

I LOVE HOW SMOOTH these Fisher Space Pen refills write! I have them in my Rotring pens. Will always choose a Fisher over a Parker from now on.
This is a great refill...

This is a great refill for the variety of pens that it fits (not just Fisher pens). The ink delivery is smooth and fairly consistent but it does glob a little bit once in a while if you do not use it often.
