Not very smooth writing. Ink is a little light in color.
I was looking forward to trying this since my handwriting is better with a smaller nib on pen, but this pen doesn’t write smoothly. I need to place too much pressure for solid steady line. I see hand cramps in future. Ink color is too light. Definitely prefer my standby, .38 blue G2 pen over this.

Awesome pens for people with small handwriting
These pens are a 0.28mm tip so they are extra fine point. I write very small regularly so these have allowed my small handwriting to be much more legible and not so bunched up. I love these pens because even tho they are fine point, they do not snag or catch on the paper, they glide nicely and do not require you to apply pressure on the top of the pen.
