I assembled the screen and have it up on the wall. It was fairly simple to assemble and the screen has no imperfections or wrinkles, that I can see.
The masking system works smoothly. This is my first screen with masking and it truly makes a huge difference in perceived contrast since my room is not totally light controled, it's in my family room.
I bought the grey screen, I had a laminate screen before, Wilsonart dove grey,I believe. It appears to be brighter than the old screen with no hot spotting and very unifrom color and focus on my Benq W5000, soon to be the W7000. I can't see any texture on the screen and is smooth to the touch. It is a bit thin, but it stretches very flat with the small springs used to fix it to the frame.
Thanks to everyone in the thread for recommending this screen. I am very pleased with the screen and would recommend it highly.
