I'm a high school student and bought this stylus to use on my surface pro computer, I've literally had no problems what so ever with it and it's so easy to write with on the computer. One of the amazing things about this stylus is that you can rest your palm on the computer whilst writing and it doesn't create any little marks. I love how you can easily press the button and it will erase the writing you hover the stylus over! Another phenomenal thing about this Adonit Ink stylus is that if the battery runs out all you have to do is re charge it, and they provide the charger with it so you don't have to buy it separately!
