I got myself a new fountain pen! (My wallet will not forgive me.)
It's a Mahjon / Moonman A2 capless EF. I really wanted a Pilot Decimo, but there's no way in hell I could afford that, so the chinese knockoff* will have to do. I went for the Mahjon over the Jinhao solely based on word of mouth advice from a friend who has tried all three (Pilot Decimo, Mahjon A2, Jinhao 10), and insisted the Mahjon was a marked increase in quality over the Jinhao, for a few scant dollars more. Of course, the Pilot was the best of the lot, but it has a price tag to match.
After reading lots of reddit posts about the interchangeability of the nib and internal mechanisms with legit Pilot parts, I went for it.
I am pleasantly surprised!
I used Waterman's Serenity Blue ink to test it. The nib is smooth, with some feedback in cases. It's not as smooth as the steel nib on my Prera, but it's certainly better than a Platinum Preppy. As steel nibs go, it's a good make. I checked the tines at high magnification out of the box, and it came well aligned. The nib is labelled EF, but it's 0.4mm, which is similiar to the Pilot F. (I generally use Japanese F nibs or standard EF nibs, so this fit my writing perfectly.) I did have issues with skipping when I first filled it, but that's mostly because I was impatient. Letting the feed saturate fixed that.
I got a version with a clip. It doesn't interefere with my writing the way some folks on reddit led me to believe. It does reinforce that I have to hold it at a certain angle to be comfortable, but with the faceted barrel it's not hard. Storing it in a pocket with the business end of the pen outside the pocket is very strange, I don't like that. (Why didn't they put the clip at the other end? Ball points do this all the time!) I want to test how it fares loose in a pocket all day. Will it leak?
Overall, it's a good pen for the price. Until or unless I discover major issues with it, it scratches the itch for a capless without having me shell out Pilot prices.
* the difference between knockoff and homage has been fiercely debated by others and is beyond the scope of this post.
