It sounds like you read
my Inka review. It's now a few months later and I'm very happy with it. It's useful enough that it's made it onto my "small" keyring rather than the "big" keyring that I leave behind if I don't have room. The writing quality is better than my Fisher Space Pen, with no ink globs. I got the cheap, steel one and it is now a bit scuffed, but that doesn't bother me.
