UC Logic P58A Batteryless Pen for D13

I bought this as a replacement pen for Artisul D10 and it works so much better. More accurate, and better sensitivity and no mouse jittering. It helped to replace the Artisul drivers with equivalent UC Logic drivers (for 9 point calibration), but it worked just as well with the default drivers also.The ruler that came with it also was great for drawing perspective lines in tools without those features (paint, word)The pen holster is functional but I use the one that came with my artisul D10 and it fits perfectly within that. Along with replacement tips.OS: WIN10
