I still have a little more house-cleaning to do... I replaced my Acute-Matte screen for my 501C with a Maxwell Brightscreen two years ago and I kept the Acute Matte just in case I wanted to go back... But I don't. So, Here's a screen that makes a world of difference if you're still using the standard screens. No marks or scratches on the screen itself, just on the frame. Looks great.
