I was excited to try this stylus -- the first I've purchased. It deserves zero stars, as I found it unusable. The pen construction is very nice -- from the retractable barrel to the hidden reset/sim-eject pin (unscrew to reveal). However, the pen tip is made of rubber. I thought the narrow tip would allow writing and drawing, but both my iPhone and iPad fail to notice the pen at all unless I use the entire large flat-rubber edge. This results is huge drag rather than glide action on the touch screen glass. I've tried in with and without screen protectors with the same results. Given it proved useless for me, I've pulled the rubber tip our of the barrel and plan to replace it with some anti-static foam.
