I like to write quickly with tall and thin strokes using the thinnest pens available. I think I like this pen so far, I have several other thin pens including a newly acquired Pentel Slicci 0.25mm and the cost difference between the two are substantial with the Pentel Slicci being much cheaper and equal if not better performance . I am leaning more towards the Pentel Slicci because the body is thin and helps to write more quickly and accurate, the needle point on the Pentel is more rigid and helps stabilize the stroke.
I like the way the body of the pen looks and feels, although it's a little too big/bulky for how thin the pen writes. This Jetstream Edge is too expensive and doesn't seem to perform that much better in comparison to make it worth the cost. The tip feels slightly loose when writing on paper so I don't feel confident in my stroke. Sometimes the ink on the Jetstream Edge doesn't appear and simply scratches the paper, it seems sensitive to slight debris on the paper (like when I erase from a Frixion pen and attempt to write over it) - whereas the Pentel Slicci doesn't have the same issue.
I've added pictures of comparison between the two pens in this review along with the other thin (and not so) that I have on hand.
In order of preference, I am leaning towards Pentel Slicci 0.25mm > uni Jetstream Edge 0.28mm > uni-ball Signo RT1 0.28mm > Shinzi Monpeluche Slim Ballpoint 0.38mm > Frixion Ball slim 0.38mm.
