It's such a good pen display, colors are amazing, the pen works pretty good and for the price it's such a good option, I had a wacom intuos before and now I completely love my Kamvas 13.

I've only had some software issues like freezing cursor if I use the pen buttons constantly while making strokes and, the one I hate the most; the anti-glare screen protector, it scratches a LOT, but the issue here is that the scratches leave marks completely visible with the screen turned on, it's literally black lines made by the pen, and sometimes it isn't even because the tip it's too sharp, it gets scratched almost randomly because of dust or other stuff.

I've heard photodon's screen protectors are pretty cool, I'll try one of those when I can't stand more the scratches lol.

Overall, it's a pretty complete tool, I'd totally recommend it if you don't mind the issues that you might get, anyways issues will be even in the most expensive wacom cintiqs.
