This product was designed to require the object to be magnified and in focus to be at least 1.5 feet from the viewer's face. Not 4-5 inches. My eyesight is not as good as it used to be so I bought this product to use when soldering PCB components. However, at 1x magnification I need to keep the subject 6-8 inches from my face, while at 2.5x magnification I need to keep the subject 4-5 inches away to be sharp. This might be good for examining an object, but it's not a comfortable distance for me to put my face in front of a hot soldering iron that can splatter lead and fumes near my eyes.
