About the usual fast and reliable delivery so I need to write anything. The end loupe does not particularly "hydric" impression. Can one expect at this price at all? Function does it already. In one of the two "lights" of the switch was broken. After I took the switch apart and the "guts" have seen, I am surprised that something very works at all. All in all, however, but ok. I can work with it and the magnification described seems to be available. Therefore, I keep them and use them often and with pleasure. The light works. Nevertheless Chaos cabling and "cheap" bulbs. If the product would have been more expensive, I would have but then sent back but at the price it is ok in my opinion ...
