This review is written off first impressions and a full day of use. I will revise this review if extended and continued use changes my opinion. Let me also qualify my review. This is my first fountain pen. I cannot compare it to other fountain pens. I CAN, however, compare it to other fine writing instruments. My favorite, to date, has been the Pilot Hi-Tec C Cavalier pens. Japanese pens tend to be the only ones fine enough to accommodate my handwriting, so I have stuck with them. Let me first speak to the appearance of the pen. The matte black is very contemporary, sleek, and attractive. I can see how it might scuff easily, but I have not had that problem as of yet. the pen comes with the rhodium nib which is a gunmetal gray color.

Now, to the real meat of the review. This pen writes BEAUTIFULLY. The flow is continuous but efficient. It neither skips nor blots. You DO have to be very gentle with your pressure against the paper, but my opinion is that all fountain pens must be this way, given the nature of the ink delivery. The clip is in a reverse position, which is a subtle but great design to help with function and to prevent potential leaks (of which I have had none). The pen is a GREAT weight. I do not like plastic pens. I like a heavier pen that pushes your strokes to be more deliberate. That being said, this pen is not too heavy. I don't get tired holding it for extended periods of time, and it is wide enough that gripping it doesn't cause my hand to cramp too quickly.

I switched the converter out for the CON-20, a squeeze converter. I like this converter quite a bit. I filled it with Diamine Blue-Black, which I find flows well, has yet to dry on me, and with a rich color. It has not clogged my nib yet. The price point for this pen is quite high, but if you write as much as I do or enjoy writing as much as I do, then you will find this very worth the money. You can instantly tell it is made of high quality materials, and was designed with a great deal of thought. I love that the nib is retractable.

As it compares to Hi-Tec C pen refills, easily the most popular pen in Asia, the Extra Fine nib is on very close to the 0.3mm, but it is not too scratchy. The nib is JUST a hair thicker than the 0.3 (close to 0.35mm?). The pen is approximately 4.5 inches long when retracted.

I am exceptionally happy with this purchase. I will be trying the pen with Pilot Iroshizuku Bottled Fountain Pen Ink, Shin-Kai - Deep Sea AND Deep Azure, Noodler's Midnight Blue, and J. Herbin Black.

I bought this pen for longer writing sessions, the sort where long pauses had me shaking my other pens to get them going again. I figured the retractable nib would be better for this than needing to remember to cap/uncap the pen.

The verdict: I love this pen so much! I was on the fence for a long time about getting one (mostly because of the cost), but I have to say I have zero buyer's remorse now that I've had it a few weeks. I loaded it up immediately with some Pilot Iroshizuku Yama-Budo, and it writes like a dream. There's a little feedback, but not much -- certainly not enough that I'd call it "scratchy", by any means.

If you've got the cash to spare, it's definitely a worthwhile investment!

Let me first qualify I'm new to fountain pens and this is my second one. My first pen was a Kaweco Sport Classic EF. When they say this Pilot is EF boy is it ever! It's like writing with a pin needle. I have small handwriting so I like the EF nibs but this one is just a little too fine. The Kaweco on the other hand writes beautifully. I did some reading before buying the Pilot and I understood the difference between Western and Japanese nibs. Now I know first hand the difference 0.2mm can make. I was originally contemplating this Pilot with a fine nib and I regret not going that route. The pen itself is beautifully crafted but just throwing out a warning on this super extra fine nib. If I could got back I would opt for the fine nib.

This pen serves me very well as the main companion for my Hobonichi planner. It's the finest nib I've ever used, yet it's smoother than some larger nibs (like my Lamy EF). I used it for a while with a converter, but I've found I like using it best with a Pilot cartridge that I refill with a syringe.

I ink it with Noodler's Polar Green, which is a tricky ink to work with. This is probably one of the few nibs that lays down just enough ink so that it doesn't bleed or feather through the Tomoe River paper in my planner. (Disclaimer: that won't be an issue with any other kind of ink. It's just because that particular ink is designed to be very absorbent, even on fountain-pen friendly paper, in order to be fast drying.)

Best of all, I love the feeling of this pen in my hand. It's sturdy and has excellent weight distribution, which allows me to barely grip it to get ink on the page. This gives my hands a nice break, since I tend more towards a natural death grip. I've had no issues whatsoever with the clip being part of the grip. I've actually found that it helps me pick up the pen and spin it to the proper writing position without looking, which is great for fast notes in meetings or while studying since I don't need to break my concentration.

I think I've found my holy-grail daily writer.

I have to say this is an excellent pen; it's incredibly smooth for such an extra fine Nib. I only use Levenger Circa Notebooks and order my papers from them, so I have no idea what it's like to extensively use this pen with a different paper quality. Also, this pen is paired with the Iroshizuku Ink by Pilot, in a Yama-budo color. The ink flow is even, consistent, and dries instantly with no smudging; the nib is always fresh even when I leave it overnight, and yes, I use highlighters over the ink, and it does not bleed (sweet!). I have to admit, the experience is incredible, and will recommend this to anyone looking for this type of fountain pen. I am an auditor and the extra fine Nib allow that I document precisely in very tight spaces, it is a dream, the only challenge is, I need to keep the other auditors away from it, at this price tag, they will need to get their own, sorry no sharing!

ordered this in 2016, it's lasted me throughout all of college. it runs smoothly, and the weight is very comfortable for notetaking. the clip seems like it would get in the way but actually it's helped a lot with my grip and it doesn't feel awkward at all.

Phenomenal pen. Owned one for more than 15 years but had to replace through an unfortunate incident. I won't consider another brand. great for sketching!

I've only been using this pen for a couple of weeks, but so far, this pen is amazing! Extremely smooth and the nib really is extra fine. Also, the pen doesn't leak at all. One thing to note is that the ink in the cartridge that came with the pen didn't flow. I tossed it and have been using namiki cartridges that have been fantastic.

Been making myself wait to get this pen...and it was well worth it! Totally exceeds all my expectations! Would highly recommend! (10 outta 5 stars!)

The heft and click of it is super satisfying. Feels good in the hand, well-balanced, and I got used to the clip placement quickly. Really comfortable to write with, doesn't feel scratchy at all (tho that might be the ink/paper too -- so far I've only used the pilot iroshizuku and herbin perle noire inks on rhodia, field notes, and mnemosyne notebooks, all of which are pretty smooth). The mat finish and black nib match my kaweco AL sport with a similar setup, so the two look fantastic together on my desk.

It's quickly become my top choice for work, drawing, and everything else. I love it.

Even my lefty friend played with it and liked it (their main comment was the placement of the clip). Not sure how it would work for more than a quick test, but thought that was worth mentioning!

Two caveats -- (1) I didn't bother with the refillable cartridge so I can't speak to it -- I'm just using a syringe and refilling the cartridge that came with it (which was fine, some lovely blue, smooth enough, opaque etc.). I might play with it eventually, but I'm pretty happy with my system (lets me mix the inks a bit to get the colors I want too...). (2) I love an extra fine nib (0.38 is my widest daily user), so ymmv (I think most users tend to prefer the fine/medium nibs).

I love this pen! It is my go-to now.
I love the finish, the weight, and the nib. I got the EF and it feels like writing with a needle, which I prefer. The clip isn't bothersome for me when writing.
I bought a decimo before buying this (I'm female w/ small hands), but I honestly wish I would've gotten this one first as I prefer it over my decimo.
My only complaint is the CON-40 converter. The converter doesn't work (won't pull up ink) on my VP nor Decimo, but that is a Pilot issue, not a JetPens issue. I have to use a syringe to fill the converter.
