Got a 0.4mm Black and have honestly been pretty disappointed in it. It skipped like crazy right out of the box, and while it's improved a little with regular usage, I still get whole letters just not appearing during writing sessions. It's too bad because I really love the design otherwise: the click mechanism feels very secure, the gradually fading linear pattern around the grip is super cool looking, the grip itself is made of a really interesting material that's some sort of hard but very grippy plastic.
It could just be that I got a dud, but there are so many good fine-tipped gel pens in this price range that I feel you'd be better off with.
