The 14kt Lamy solid gold nib is an absolute pleasure to write with. The medium nib I picked for the writing samples wrote with a nice, wet flow and glided across the page with every word. Although the Piano Black is a glossy, lacquered finish, I found no trouble in being able to grip and hold on to this fountain pen's wider grip area. Since most fountain pens usually have a narrower section to grip, the grip on the Lamy Dialog 3 takes a little getting used to, especially if you write with mostly thin pens (like a Cross Century).
Overall, I was extremely impressed by how this pen handles around the curves and responds when you accelerate (handwriting speed, that is). It can keep up with fast writers and those who like to go big and bold.
Functionally, the ball valve mechanism does a great job at keeping the nib fresh with ink. There were some issues of dry-out with the first iterations of the Dialog 3. Lamy has since addressed those imperfections in the newest models. In my time spent writing with this pen, I experienced no issues of hard starting or skipping due to ink drying in the nib. If you're looking for a quick draw fountain pen to take on-the-go, the Dialog 3 is a superb solution.
