This product is a very good size (slightly smaller than an actual pen), and therefore provides excellent grip. The hollow rubber tip makes it possible to damage the screen and leaves no trace on it. The plot is accurate (used with several pro drawing applications, no offset problem) and the little tip for jack is very useful in moving to avoid losing it.
Also tested on iphone, same observation: the stylus is really excellent and allows greater precision in certain gestures.
At first it seems a bit pricey for a stylus, but when you see the user experience feedback for the first pens price, it seems to be a good choice as long-lasting and effective.
