I am pretty pissed! =(
I have a Wacom Cintiq 12wx since last year and I love it to death. I love it so much, I decided to spend 30 Euros for a protection, so no scratches or anything happen to the display (because I already got one scratch, almost got me a heartattack).
I got this Invisible SHIELD a while ago and applied it a while ago, but didn't use the cintiq until now, because I was busy inking my mangapages the traditional way.
Now I wanted to start doing the screentones with the Cintiq and now I realized, that his goddamn Invisible SHIELD sucks to work on. It is made out of a Material that feels like rubber when trying to draw on it.
