I'm past my 90 days to return it. I didn't change the material. I am using what came in the kit. It is the Lunar 4K 0.85-gain screen material. Other than that, and price, I have no other issues. Looks great on the wall and all else looks great. If I ever change the screen, I'll probably try to build my own first.
