Good grip, the stylus is compatible with the Cintiq 24HD for anyone that asks this question. The calibration of the stylus is any sequence recognized my Cintiq via Corel Painter software 2015 X3 Corel Painter, Illustrator and Photoshop. Frankly I do not regret my purchase although I still find that it is not for the price especially given that there is no more mine apart from the base.
