I have purchased three of these with poor performance upon receipt. JetPens provided technical assistance immediatly to fix the problem.

The only issue is incomplete lines. As if the roller ball was sticking or the flow of ink was stalled. This was more pronoun on scientific notebook use. It did perform if the length of time on paper was short and the paper was thick.
If I could get this thing to work it would be perfect. I love the color and line when it works.

End result = a bit of frustration and ~$20 down the drain.

This is a great ink with wonderful color, and it writes exceptionally smoothly. As I noted in my review of the same refill in blue, it is a needle tip rather than conical tip. I find the needle tip a bit too flexible, but I love the color and flow, especially on the Sigel Conceptum paper. It also works well in a Rhodia webplanner, and the look on white paper is considerably more blue than on the cream of the Sigel.
