Before I get to the many advantages (see below), the only thing that bothers me is that the installation was difficult due to my housing. Easy install without the case but after putting it on I found that one corner of the case did not mate with the screen protector which resulted in an air bubble forming at the edge where the screen protector meets the case. So I installed the second screen protector that came with the case while the case was on and the problem was solved. My case is Zugu 12.9 iPad Pro 4th Gen. Looks like Zugu has an infinitesimal machine error that doesn't make the angle perfectly symmetrical. This is a premium screen protector! Ideal for painting as it slows down slow and even broad strokes. Writing is a dream too. Great feedback to get a better feel for your pen. Not to mention that when using the touchscreen with my finger, I loved the "warm" tactile feedback from the quality of the paper. In any case, this product needs to be more sponsored in the search. Above the level of the main competitors in the field of protective film for drawing / writing. I found it through a comparison test on YouTube: half the price and better quality.
