Bests & Worsts Reviews from Amazon

It's a good concept, a visor- style magnifier with flip- down, interchangeable lenses in several convenient magnifications, with a head mounted light aimed at your work. The problems though are many: the headband is not very comfortable and does not stay securely in place, so when you lean over, the visor may fall off; the plastic lenses snap into the visor. The place where they attach is thinner than the rest of the lenses. The first time I removed one, it broke. Not only does the visor itself flip down but so does the lens. Unfortunately, the lens does not stay in place, it gets loose after a few minutes, and then it swings every time you move your head, this makes it useles, because it means the focal point of the lens keeps changing and you cannot bring your objective into focus. Thus, less than 10 minutes out of the box, my magnifier was not in any way useful in my work. I would have been better buying a set of 4 different magnifiers, one of each strength. I may salvage this by supergluing several of the moving parts, but it is defeating the original purpose.
