The fact that there are no replacement tips for these Samsung pens is an outrage and stupidity beyond compare! The stupid way of attaching the pen via a magnet (instead of being able to insert the pen into the device, as with earlier models) always leads to the pen hitting the floor. And at some point, the tip is inevitably ruined! :-( And Samsung really thinks you have to buy a new pen every few months! :-(( Are there any replacement tips available from other sources?
