This Stylus feels much more like a pen than the original asus stylus. The clip on the pen is nice, but it prevents the pen from going into the stylus compartment. (might fit if you break the clip off). Not a big deal, I usually keep it in the case's sleeve.Pressure sensitivity works, writing harder does make thicker lines. (tested in OneNote)Erasing works too.The button is a nice feature, makes right-clicking much faster. Basically, you just press in the button and tap on the screen = instant right-click. tap and holding for right-click still works as well.
