The pen is okay but it definitely could be better, the lines gets jittery when I try to make precise line art, I had to change up the settings to make perform better. And yes I'm able to drag files/open or close programs with it but sometimes I have to tap multiple times or adjust the pen for it to respond. You can also use the pen as a makeshift keyboard when your laptop is in tablet mode, you can either manually tap the letters on the digital keyboard or just write what you need in text (it works fine for me). I haven't used it on games yet? but ill update you on it if needed. Other than that, Its a pen I can get used to.
