The GM Screen seems made of material designed to stop a fast moving die and is very sturdy. I'm also pleased to see it has the common status effects details and all the charts for the skills on it. Not sure I like that its so tall - my recent experience has shown that tall screens get in the way lately, what with all the miniatures and movement on the maps.
Looking forward to trying it out in actual play come my next session.
I received the GM Screen yesterday, and I must say that I really love it. Easily the best GM screen I've seen for any game. What I really love about it is that you can use it quite easily even if you don't use a GM screen, since it opens up like a booklet.
I agree that it might have been more practical with the pages if it had been lower, but I think that it is probably more sturdy as it is now.
