Very useful in many ways

I have a double concave image to use with art to test accuracy of portraits. The double concavity gives you a virtual image as if you were looking at your drawing in a mirror, except it's not upside down. Don't ask me how it works, but it makes it easier for you to see what's "off". I also bought a double bulge just because it was included, but I've used it several times before to increase the fine print or add reference detail to a drawing. I don't know why, but I find it much more comfortable

Pros
  • Made from high quality optical glass
Cons
  • Questionable purchase for the elderly
