Title: 3x Magnifying Mirror
Review: Some of the mirrors are not optically "perfect". These mirrors magnify because they are curved. The problem is that if they are not curved perfectly, the magnification changes as you move around. My wife dislikes the one she ended up with. I have noticed that some magnifying mirrors are now advertised as "optically perfect", which indicates other people have had the same problem. My wife gave one of the mirrors to a friend, who is happy with hers - so I do not know if only some are poorly built. It may have been built by the same company that built the original Hubble telescope.
