I was finally able to do some good tests with my new focusing screen
and let me tell you it is all that and a bag of chips :)

Installation was a breeze, but in the future I will be wrapping a bit
of cotton tightly around my tweezers, to avoid any scratches. I also
had to remove my copper shim that lays under my factory focusing
screen. With that shim in I was not getting proper focus, after
removing the shim and doing a few more test shots, I was able to
verify that I had dead on focus.

I do a lot of nature macro work and this requires very critical focus,
I also use a lot of older manual focus lenses, they give me much
better quality glass at prices I can afford. This screen has made it
possible for me to use my manual lenses in places I could not before.
My viewfinder is brighter now as well, another HUGE plus when I am
shooting live concert events.

A good example of critical focusing would be a shot I was able to get
a couple of days ago. I was using a bellows setup with a 75mm enlarger
lens, the depth of field when using this equipment is very short, the
difference between in focus and blurry is measured in millimeters.

I posted three images in the photos section, in the folder labeled
Macro. I honestly do not believe I would have been able to properly
focus on the tiny ladybug without my new focusing screen.

I would highly recommend this screen to any of my fellow photographers.
