I have never liked using a GM screen. I find them flimsy and cumbersome. They are always fall over or flop around on the table and always seem to wrinkle or rip in my backpack.
This screen will do none of those things. It is made of a similar cardstock as the cover of a hard-back book. It is four letter size panels arranged in a portrait orientation. It stands up well, even when dice hit it. The stiff side allow you two fold in two of the sides, making a sort of mini-screen (though you can't read the tables) if table real estate is and issue.
I will be using this screen at my next game, breaking my 3 year boycott of GM screens.
