I installed one on my 8x10 'dorff several years ago. It helps. The good news is it's brighter, the bad news is it's brighter head-on only. Like a cheap lap-top screen you must be on-axis. It also helps if you are back far enough to use binocular vision on a single spot. This usually leaves out those of us over 45. However, my optician and I have managed to stay one jump ahead of the aging process, and if I'm wearing the correct glasses I can get the best out of the Beattie screen. It goes BEHIND the ground glass (closer to YOU), with the engraving away from you.
