It is affordable, binocular, and lets me work hands-free. I like the 2x
objectives coupled with the 2x ocular attachment. That lets me get a
good binocular view at 2x and then flip the ocular in front of my
dominant (right) eye for the aggregate of 4x magnification. The unit
supports a couple of different lighting attachments but I have nice,
bright fluorescent/incandescent adjustable light fixture that works well
for overhead lighting and an artist's lightbox for backlighting, so I
don't find the need for another light source.
