The first thing you will notice when unpacking the screen is it's sturdiness. This is really a hardcover screen. The material is best to be compared to the material used for the boards of board games. Comparing it with my old GM screen one folded page has the thickness of the complete old GM screen.
So what do you get? Coverart with all the iconic pathfinder characters facing your players. You might like or hate the style - as a Pathfinder Society GM who hands out a lot of pregen characters to new players I like that the screen includes the pregens I just handed out.
Inside you have 4 pages roughly A4 sized (it's the US format) with information. The first two pages are about skills, difficulty of skill checks, modifiers.
Then follows 60% of a page with combat modifiers - for the attacker, defender, Combat Maneuvers, two weapon fighting, Concentration checks. The remainder of the page is used for common conditions - like blinded, broken, confused, etc.
The last page is filled with weapon hardness, substance hardness, object hardness, Experience awards and treasure value per encounter.
Throughout the screen you have page numbers listed to allow a quick way to find the relevant information in the Core Rulebook.
All in all - a well deserved five stars in my view.
