Who has big fingers knows the problem when typing on tablet or mobile phone, often you skin next to ... So I was looking for a pen is to facilitate my entry and he should act like a real pen. I thought that was not a problem, however, most pins as short that you get to keep a cramp after long, unlike here, the pen is sufficiently long, just like a normal ballpoint pen, the touch screen tip is hardly noticeable, the design is simple and successful.
+ Length of the pin + Simple design - Clip on the cap could be better.
