So I actually used one of these pens for day to day writing until it stopped working, and simultaneously used a Uniball Signo 0.28mm for the same purposes until it ran out of ink. I filled up one Doane pad, and two Clairefontaine pads with notes. I'll compare the two:

-The Uni-Ball pen lays down a thick, smeary river of ink, while the Pilot pen is far more sparing. I used both pens at about the same rate, and the Uni-Ball ran out when the Pilot was at about 2/3 expired.

-Both pens stopped working at around the same time. The Uni-ball ran out of ink, but the Pilot's tip just stopped functioning for some reason. There was no obvious mechanical failure, but with about 1/3 of its ink reservoir remaining, lines became spotty, faint, or not inked at all. I'm not very hard on these pens-- My writing style does not put very much pressure on the tip.

-The Pilot pen made the better line. Lines had superior definition, and smudged less overall.

-The uni-ball pen made a much more consistent line. It smudged more easily, and had poorer definition, but it performed in exactly the same manner until it ran out of ink. The Pilot pen sometimes took a few lines of writing until it started acting normally, and the quality of the line varied from day to day and line to line.

-Both pens were very nice to write with. The Pilot pen had a slight advantage, but both felt very good compared to other pens.

It performs excellently when you first buy it; the lines are finer, the writing crispier, and writing in general gives a much better control in comparison to Ball pens and speed in comparison to traditional Fountain pens.
But as the weeks pass by, its quality starts falling. The writing ink becomes inconsistent; for example, if you have to write "following", it will write "foll" well, then skip "ow" and again write "ing", and this problem happens a lot. Secondly there is this problem with the ball at the tip; I have bought two Pilot pens till date, in both cases, the ball just disappeared one day! And since there is no refill that you can change, basically your whole pen becomes useless because of the ball falling off (or going inside, because sometimes if you keep the pen lying useless for a year or so, the ball comes back in place). Thirdly, the pen is just not the same as time goes on. I mean, by the time the ink runs out and you have to do a refilling, the tip becomes quite blunt, so the crisp writing is no more and it starts feeling like a ball pen. Add to that the inconsistency, and you have a quite frustrating experience. Finally, I made the mistake of washing the pen couple of days ago, since the ink dried up after not using it for so long. Now the pen doesn't write a single word. Fill it up with as much ink as you want. It will start leaking from that small hole, but still it won't write.
Overall, the idea behind this pen was creative and innovative. But it gets old way too quickly, and the problems are serious and common. I will give it a 2/5 rating.

This pen lays down an amazingly fine line. However, I usually write with the pen at a heavy slant (I'm a lefty) and the Hi-Tec-C doesn't like that one bit. When taking notes in class, the ink frequently sputters which is, needless to say, annoying. They work just fine for my girlfriend though.

These are great pens, and have become necessary thanks to my particular art style. If anyone's wondering, they're pretty smudge resistant. The only part I don't like is how the line has a tendency to gum up. Nothing grills my eggplants more than my fine, consistent lines suddenly running out. The flow could be better.

When I first got this, it would stop working for a moment and I would have to scribble until the ink came back. It tired me out so much that I stopped using it. Now, the pen seems to be acting normally. I really like how thin the tip is and when I write with it, it almost feels cushiony. I use this for school and I've never once seen it bleed or smudge. Worth the price.

I loved them! The one that i gave away was really loved and they write so smooth that when others saw how thin, and great they were they asked me where i had gotten it from. I have a feeling i will be oredering quite a few more soon..

Hi-Tec C's have the thinnest lines around which is why I used them for years, but it's the consistency I have a problem with. I'm a concept artist in the video games industry and I used to love these pens for thumbnailing at work or just doodling in my sketchbook. Lots of artists use Hi-Tec C's and personally vouch for them. However, I've found over the years that the lines from Hi-Tec C's tend to skip more and more as you frequently use the pen. You also have to press a bit harder with these pens, which can help with your control but leads to a scratchier feel, wears out the tip and leads to the line skipping I mentioned before.

If you like to draw with super fine-tipped gel pens, my recommendation is the Signo (Uni-ball Signo UM-151 Gel Ink Pen - 0.28 mm - Black) They're cheaper, the line is almost as thin, but they're sooo much smoother and far more consistent. Using one after drawing with the Hi-Tec C felt like drawing with warm butter. Plus, and this is just my opinion, Signo's are far more comfortable to draw with for hours on end.

The hi-tec-c 0.3 mm and the zebra sarasa 0.3 are my go-to pens for all math and writing work.

Writes with the diameter of a pencil but with the smoothness of a pen.

This has a nice fine line, but I find it a bit to "scratchy" for my taste, so it's out of the pencil case and into the drawer.
