first drawing on new art computer and with new Gaomon PD1560. Mixed opinions.  
screen protector is bubbly garbage - threw it out.  
screen is nice and idgaf about accurate colors, looks well enough to me  
doesnt always line cursor up with pen well. especially, tilting pen can put your pen tip very far from the actual cursor. mapping not always effective. but you can get used to it, once you see where the dot lands, you just work with it.  
lag though, doing quick sketches, you just see the cursor lagging behind you. i find it incredibly distracting. but doing slower strokes for inking, doesnt bother me as much.
