I love this pen so much! I've been using it every day (on every kind of paper from the best to the worst) and it's been remarkably consistent across all papers- I've even tested it side by side with the same ink in other pens and found it to be the most consistent of the bunch.
After two weeks use it has some micro scratches from posting- it does post well, although I don't always bother to post it. I haven't had a single flow issue, no skipping, hard starting or anything like that (I carry it clipped upright in my purse). It has some really delightful feedback that's hard to describe. The cap-off time without drying out is impressive, although I haven't actually timed it.
