content: Not a bad product for the price, but can be difficult to get set up without all the right stuff. I bought it to use with a Nikon D5000. Initial problem was I couldn't get it focused with either the 18-55 or the 55-200 lens. The extension tube needs to be just a bit longer. Fortunately, a +2 close-up adapter between the lens and the copier did the trick. The 3-slide holder is tight and difficult to use with older, paper slide mounts. It would have been more efficient to just eliminate that part altogether and drop single slides in from the top. Everything seems to fit too tightly for easy use, but I guess that would loosen up over time. All-in-all it does a good job for the price once you get past the considerable setup curve. Comes with no instructions - you have figure it out yourself.
