I was looking for a pen for my iPad for the preparation of drawings and notes and I have to order this Griffin Stylus and Stylus Just Mobile and compared them. For drawings they are both very suitable, for example in the Adobe Ideas app. Written notes require practice and succeed only after some time. Both pens are comfortable to hold, with the Just Mobile stylus little more scores against and big hands come. The Griffin is well suited for small and "medium-sized" hands. Positive on Griffin stylus are his clip, the eyelet for attaching a lanyard or the like and the space-saving accommodation. Although the pins are certainly not cheap, I decided for both: the Griffin on the go and the Just Mobile for home.
