A note on this video review: I purchased this pen with my own money, Ackerman didn’t sponsor this video, and I doubt they would like this video.
This pen is not for someone who does not like to tinker with their pen. In order to reset the pen you must take it apart and use a bamboo skewer to push the feed out the front of the pen. Then you must push the nib and feed into the pen at the right spot so the nib will seat itself into the pen properly and so the nib and fee will be aligned.
Mine was not set properly and the nib and feed were out of alignment with the original location of the nib, this caused the nib to be too far out and to not sit properly on the feed. Annoying. I had loads of railroading and blobs. Awful.
Once the pen was set up properly it works really well. I ordered a few new feeds to adapt a few of my other pens to this.
Anyway, my video does not show this set up process, but is me talking out the above and testing the pen before and after resetting the nib and feed.
