I bought a tablet and it arrived 3 days ago, small scratches are visible at counterlight, to stop scratches i was told to use a sheet of paper in top of the tablet, which worked actually, but i just realized that the paper sharpened my pen nib after like 4 hours of gameplay, i have the Gaomon S620, and i want to know how scratched your tablets are and how they work to have a comparison, thank you.
