Absolute favourites
These are my absolute favourite pens for everyday use, and for drawing over watercolour paintings. I hold a pen in a slightly odd way, and many pens simply do not write for me because of the angle of the pen on the paper. These, however, are totally forgiving, and give a really clear line of consistent thickness, which is really important to me when doing fine 'doodles' on top of watercolour paintings. there is absolutely no drag or 'stop-start' of the pens even on 'rough' watercolour paper. I also use the 0.28 ones, but they are slightly more difficult to get hold of.

Excellent pen.
Beautifully sharp. This is the closest I've come to a fine nib fountain pen. Flows easily with no scraping or missed strokes. Bought a box of 10. I'll be reordering again.

Long lasting, very fine lines, comfortable to hold.
I wanted a nice fine pen for writing small and drawing fine details in diagrams and found these suggested a couple of years ago. I've now gone through 20 of these pens and have loved 19 of them. (1 was a little scratchy, the rest were as smooth as I could wish for) You might think 20 pens in two years means they don't last long, but that's not true. I write a lot. I know from having typed up my notes that I have written at least 200 thousand words in that time. And that's not including the pens people have borrowed from me and not given back because they fell in love with them too. It's difficult to get the 0.38mm in the UK, so I tried the 0.7mm too. It is wonderful and fluid, but the breadth of the stroke is such that it's for a larger writing style.

Cheap and overall nice but somewhat unreliable
These pens are great for writing small and slow but I found them to be unreliable in how the ink flows from the pen. Sometimes (and this is confirmed with several pens) when I write the ink just stops coming for a second so I have to go back and re-write words. Also, for the most part the ink is intensly black with good print on the paper and then suddenly goes gray because of insufficient flow. I like the UM-151 but I need something a bit more reliable for my kind of work.

Wundervoll dünne Strichführung
Sie sind so dünn, dass man mikroskopisch klein schreiben kann. Dabei ist aber die Tinte weich genug, damit man nicht kratzt und krakelt. Die Tinte franst tatsächlich nicht aus, trocknet wirklich schnell und ist wisch und wasserfest. Der Tintenverbrauch geht. Ich habe einen markiert und schaue seit dem, wie schnell die Tinte von der Markierung abwärts sinkt. Wer den Gelschreiber für die Schule kauft, sollte sich lieber ein günstiges 10er Pack holen, statt ihn einzeln zu kaufen, weil er sonst schneller als erwartet ohne Tinte dastehen könnte. Inzwischen bin ich ein großer Fan aller Uni-Ball Stifte und das sind meine absoluten Lieblinge!!! PS.: Nachtrag einige Monate später - Für das nachziehen der Außenlinien einer Zeichnung, sind sie nur bedingt geeignet. Der Radierer läßt sie IMMER verschmieren. Das hat scheinbar nichts damit zu tun, wie lange die Schrift trocknen konnte. Also ACHTUNG. Wem diese übrigens zu "dick" sind, kann noch auf 0,28 runter.
