Works well on ASUS UX370Ua as a Microsoft ink pen. had to install driver, but was no hassle. very responsive very nice to use. The lack of a Bluetooth button has not been obvious yet. all apps i use, (Inkscape, Scrble and Sketch book.) all recognise the pen as soon as it comes close to display. pressure sensitivity is perfect for note taking to even a artistic use. Windows is good in recognising the pen even when your palm hits (rest on) the screen. the only app making the palm error once was Scrble. Also switching between my screen and a Wacom Pad is easy, just holding two buttons down and you make the switch. Great tool.
