It's true, this magnifier is slightly heavier than other magnifiers, but you can not outwit physics, so if you build a big magnifier glass, then it is of course heavier than plastic magnifiers, because glass is now even more difficult. Whether and how the / users / get along in order, everyone must know himself.
What could I complain about would be the, sometimes a bit too small for me gain (2.5), but that makes again possible to read larger cuts, will in the end, by the larger image circle, reading but pleasant. I often need to small fonts, for example, to read in manuals of devices, which are now so small that even people with no eye problems have difficulty reading it. This is probably due to miniaturization, but I do not understand how you can print at all so small texts to any destination. Well, but that's another question.
The fact that these magnifying glass comes with a cloth and detergent, which makes the whole thing really makes sense, so 5 stars from me.
