Got mine today. I am a bit disappointed. For some reason I have to apply quite a bit of pressure with the stylus for it to register fully otherwise its dots when I try to draw a line so writing is well not that great. Not sure if its my digitizers but tried to use em on a Asus T100TA, Nexus 7, and 5. Going to try it on my coworkers ipad later. I did notice if I hold only the clip end, the stylus doesn't work on its own so I assume its using the battery to not generate its own capacitive field but amplified one from your hand.
