... I will not be as negative as what I read in the comments. This pen works well, is responsive and relatively accurate, provided you use the right App and well set. Oddly, it is with the application Bamboo Paper I had the worst results. By cons, Tayasui Sketches works very well. For taking notes, I use Noteshelf he should not hesitate to be set, including the position of the hand. The correct choice for this setting is essential to prevent the gap between the point and the line. Do not hesitate to try them all, even those that do not correspond to the true position of the hand. But it is GoodNote who wins the prize for the best integration. With this pen, we must grope not bad for a correct result, but no more. Therefore, the price seems a bit high. The tip, harder than conventional rubber tips, is pleasant and not too noisy. My tests were done on an iPad Mini 2 with a screen protector.
