The function of the stylus on my iPad Air with Penultimate or Good Notes is outstanding. To the other side with the pen tip, you do not say much, just works and also writes beautifully clean yes. Overall, the pen fits comfortably in your hand, no matter how I use it around. Not too heavy and not too light, not too long and not too short. At least for me. Actually I wanted to forgive five stars for this double-functional Stylus. Unfortunately, however, the point is obviously very short-lived, because after just a little over a month, she's already broken and I have to, I think very expensive to order replacement tips. Since I get a little feel that the wear is inevitable. Therefore, I give only four stars.
