Pentel Hybrid Technica Retractable Gel Ink Pen - 0.5 mm - Blue

Smoothness: Okay
Precision: Okay as 0.5 mm
Weight: Light
Grip feeling: Rather thin and therefore not very comfortable.

Overall impression: Everything is okay but the design is not ergonomic. I recommend Pilot G-Knock 0.38 mm which feel appreciably more comfortable everything else being the same. (G-Knock 0.38 somehow is as thick as 0.5 mm)

Excellent pen for note taking! nice, controlled and THIN lines, good size barrel, does not scratch onto paper, etc.

Perfect pen! Very smooth, no skipping. Clean lines. Comfortable grip. This picky left-hander highly recommends it.

Awesome pen! In the same class as the highly-recommended JetStream pens. Definitely worth having one or two in your collection.

I don't like this one.
