Smoothness: okay
Precision: okay
Weight: light
grip feeling: okay
cushion: solid

Overall: Okay. I personally prefer Pilot G-Knock Retractable Gel Ink Pen - 0.38 mm
for better grip and better nonslip feature of the cushion.

This pen is pretty good. The only thing that I don't like about this pen is the ink color. The color to me is not a light blue. Its too dark for me, but it is lighter then a blue color pen.

I think the Uni-ball Signo DX 0.38mm writes smoothly that this pen. As I try to compare the 2 at the same time, for the DX, the tip glides smoothly as you write. For this pen, the tip comes too sharp that it doesn't glide.
