I was quite slow to jump on the writing instrument bandwagon, but after dipping my toe in with an inexpensive RITR pen, I'm now slowly finding myself in deeper and deeper waters. About a week ago I received what I consider the optimal pen available, based on my preferences, the Urban survival gear TiScribe mini. The problem I'm having is that it writes really bad, or should I say intermittently. When I first took it out of the package I had to engage it on paper for an eternity before it finally put some ink spots on that paper. But even now that the ink can flow continuously for a while, it will intermittently fail to deliver ink on paper. I've used cheapish pens my whole life and been pretty satisfied with the result. I guess this Schmidt Easyflow 9000M might be delivering questionably nicer lines, but this is just too unreliable to bother using it. To me it feels like there might be a QC issue like an uneven or damaged surface on the ball. Maybe someone more experienced could help me determine if this is the name of the game when you move into more precise cartridges, or if did indeed get a bad sample?
