Query: Works really well when you adjust it

Mounted on my 28-105 canon lens but it cropped half the picture off. Then I learned that by loosening the screws on the metal holders I could slide the unit up and down and adjust the viewing area. I have since copied about 75 slides and they turned out very well. So much easier than scanning them with my slide scanner. I can then download them and work on them if necessary. It is great fun to bring back the America my aunt knew shortly after World War II. I can share that world with the rest of my relatives! Results could be sharper, but it is pretty good for what I am trying to do.
