Review at the head

I would not have thought so. To the price but I have bought two of these headband enlargers. One for my master goldsmith (who is very enthusiastic for the rest) and one for me. The advantages are obvious: You can continue to work with the spectacles (which also means another magnification that can be added to it!), You can fold up the second Vorschaltglas and outside addition Upstream even a magnifying glass. The, and that's the only downside to this headband magnifier, has only a very small, acceptable cut, but with a little practice goes well, the ultimate for about 10 times enlarged detail.

Furthermore, ideal for sanding and polishing - so you have the same eye protection. Preferred working order (with glasses and glasses both upstream): Movements dismantle, remove pointer, polish housing of wrist watches and grinding etc.

The build quality of the construction entirely of plastic (the "glasses") produced is simple, but easy. On the ring side that rests on the forehead, one should perhaps apply some foam, so in hot weather by welding the whole will not slip. The hinge for folding the front end could rest a little harder. The batteries are worthwhile just going to Vorschaltlupenseite, but then bring beautiful light centered by inwardly sloping attachment.

All in all: A good part especially at the price. Of course, a counterpart of Leitz because you pay but the 320 times the price ... ;-)
