Fountain pen Hongdian A9: Review

(English & French subtitles)
The Hongdian N10 fountain pen was released a few months ago with a new #8 nib.
Now we also have the Hongdian A9.
Even if the Hongdian A9 could be seen as an N10 with a converter, this is not the case.
There are indeed more significant differences, both positive and negative.
In this video, I will review 2 Hongdian A9 pens, while comparing the A9 to the N10 all along the video.

I'm sorry to see that you've had a problem with your blue pen. My pen arrived this afternoon; and so far; the cap ring is in place, but I will be keeping an eye on that. Thank you for informing us of this issue. I do; very much; like the brown pen. That color seems to highlight the pattern, more than the blue pen. The blue pen is very dark and I wasn't expecting that. It is difficult to photograph or video, because of this. Once again, you've given us a thorough review. Thank you.

For the blue pen I've fixed it no problem. Good if you don't have this problem, I hope it will remain exceptional. My favorite color is usually the blue (like you if I remember well): but I can tell this brownish color is absolutely stunning. Clearly today my first choice over the blue version. Thank you for the comment.

Follow up question; have you had any ink leakage or burping?

No leakage or burping. Have you experienced this problem ?

@@UneFontaineDePlumes my daughter bought the same pen. Last night she uncapped it and the cap was full of ink. The pen was lying horizontally. I was thinking that mabe ebonite feeds are more prone to expansion during hot weather? My pen burped ink, when I first inked it but it was still warm from being in the mailbox. After it cooled, I have not had any problems. Hopefully, it was a one time event and she won't have any more issues, but I told her I'd check with everyone I knew, who had purchased one of the A9 pens.

@@teresaharris-travelbybooks5564 May I propose 2 points to check ? If the problem occurs again. First is just trying to change the converter. Second is to check the nib/feed position in the housing: the housing is not symmetrical (like for jowo). Feed and nib can be removed. then when you have a look to the housing, you will see a kind of small "border". Half of the circle has the border, other half has not. The nib must be inserted exactly where the there is no "border", the feed where the border is. If no there is a lot of "chance" to have ink linkage.
