My Asvine C2000 is still not sealing well even with an added o-ring. Bummer. Might need to try a different o-ring and/or a different ink.
It's not evaporating much from the converter but the nib won't write until I rinse/wipe it a bit and work the ink back out. It's possible it's clogging (the ink in it is a heavy sheener), but it feels more like it's dried out.
So while it looks great, and writes well when it does write, there is definitely room for improvement.
