Excellent pen, I work with my illustrations on a tablet Archos 70 Titanium (game entry so) the contact is pretty good but it was choppy. By searching YouTube, other people were in the same case. A piece of aluminum or paper of the same type (eg bag of chips) introduced between the tip / ball and the disk and the problem is solved. Best contact fluidity. By cons attention, drive very very fragile, already broken after one week. Considering the price of the stylus, additional disk in the box was not too much.
Type "How to Fix adonitjotpro" in YouTube to see how to proceed)
