Does what it was designed to. Not for everyone or everything. Not a "regular" pen.
There isn't anything spectacular to be expected from this pen. Nothing makes it super special, smoother, or more refined than say something from the Dr. Grip series. However, it does what it was designed for. The extremely fine-point is akin to writing like a pencil, but not just any pencil. It is like writing with a mechanical pencils. The mm difference is even smaller than the famously 0.5mm that is still very popular today. So each stroke is extremely fine. At a distance you can barely tell if something was even written, that's how fine your lines will be. This is not a pen for regular use. This is not a pen for clerical use. It is definitely purpose-designed for specific use and that would be for where-ever fine writing is required. I can see the application of this small mm edge point being particularly useful in architectural, mathematics, engineering, and even music composition fields. If you want a pen for regular notation and scribbling, just get a Dr. Grip.

obsessed, love writing small
some people just have the urge to write small. this pen does such a gorgeous job of it, highly recommended. heavy and firm and perfectly sized in the hand, a tiny bit at the finger grip, almost all of the weight is at the fingers, not at the top, so the fingers have complete control of the pen

Feels like its out of my tax bracket but I don't care, becausec this is my new FAVORITE pen!!!!
This pen writes so darn smooth and tiny! Perfect for squeezing lots of info in small spaces. I love thin smooth lines and so many pens that I have used in the past skip so I sorta expected this pen to do that, but I was pleasantly surprised! This pen has got some decent weight like it can probably cause some decent damage if thrown type of weight. Thats probably not useful info, but anyway the pen is worth the price. Buy it!

Use a light hand when using this pen
This pen is an absolute gem. The 0.28mm tip size allows for thin lines, similar to those of a sharpened pencil. The ink is dark and easy to see on the paper despite the thin lines. You will need a light hand with this pen. For a few reasons. Reason 1: The small ballpoint is prone to getting jammed with paper fiber if you write too heavy. If this happens, just scribble off to the side and the ink should flow again. Reason 2: The tip is delicate. If you write with a heavy hand, you can dislodge the ball into the mechanism. Reason 3: The tip is so sharp, a heavy hand will cause the tip to go through the paper. For those who like the aesthetic of the pen, but find that 0.28 is a little too fine, there is a 0.38 variety as well (in a bunch of other colors). You can also swap out the ink for jetstream multipen refills that go up to point sizes of 0.7mm.

Wonderful pen
Love the way this pen writes. Feels a little plasticky. Looks great on my pocket sized planner. Can't use thick pens in it because it overwhelms the page so this is great.

i feel like i can write on rice with this pen
The mm is so small I feel like I could write on a piece of rice lol. heavy body and smooth it hasnt skipped on me yet. its not the pen's fault, my handwriting horrible bc im so used to writing with 0.9mm-1.2mm pens so it looks super shaky lol

Disappointed.
I cannot believe this. I just spent ten dollars on this pen, thinking I’m splurging a little on myself. NO! This was so not worth it and I wanna cry. I’m a mom. I never buy myself anything just for me. Except the love pens. I wanted a nice pen. To start the barrel is not comfortable. The point wobbles ever so slightly. The ink is not great. It doesn’t flow well. It scrapes along the paper and midway thru the sentence it starts to drag the paper! Like when your bikes brakes lock up on you. It’s just not great. Maybe for technical drawing or drawing super fine detail. Look, I buy pens. That’s my thing. So 0.28 mm part didn’t worry me. I expected it to be fine point. That’s not the issue. Maybe it’s the oil? I’ve never had one before. But it’s not for writing. Not worth the money. And there’s no weight to the pen! It feels cheap.

I preferred tiny ball point as I write small. This feels like a mechanical pencil which I like.

Me preocupaba que mucha gente decía que no tenía escritura fluida pero nada qué ver, es algo muy delgado y no siendo tinta de gel como otras plumas es sutil el trazo que deja, les recomendaría ver videos de cómo pinta si buscan algo en particular, pero a mí me gusto, el mecánismo es bueno, la sensación de escritura así como el peso frontal también, no es toda de metal como podría parecer, pero aún así se siente de muy buena calidad.

Genuinely the best pen I have ever written with. The thickness of the lines is perfect for my handwriting, and I can't stop using the darn thing. I had read a previous review that the ink in each of the cartridges is low and requires constant replacement, but I didn't really see that. With constant note-taking every day in university, it lasted a solid 1-2 months before needing a refill. My only critique is that you do need a rougher paper sometimes, with very smooth papers not accepting ink from the pen as well (though this could be user error). Overall, I'm buying another one.
