After I had made this part deal, I now have a great headband magnifier. But who wants to have a tinker unit only cope before it can be used as intended? And that's why there was only one point: The desired setting of unreasonably hard by prolonged use of the headband can not fix and goes right back up. In addition, head hair remains in this scrap-closure hang and be rooted in losing weight. Remedy: lock the desired setting with Leukoplast and also taping the entire closure order. Optionally additionally wrap against the painful material hardness with fabric. The two folding hinges for quite heavy loupes are without any maintenance, so do not line up and close look bangs completely unfounded on the nose. Remedy: encase hinges with good adhesion and flexibility constant Knetdichtung from the plumbing DIY. And already the hinges remain in the desired setting are, do not fall off and can be preserved (!) Also set differently. Positives: several magnifying glasses are to choice and can be combined with one another in pairs, even as there are 2 magnifying glass holder, which can rest on one another. The appropriate distance to the object is at the many Lupe settings naturally vary in size and definitely not too small. With an appropriate size magnifier so no need to fiddle around in front of the magnifying glass, which is unbearable for many other headband magnifiers.
