I have the glasses for a few weeks. Pros: Well made, good optical quality, and of course, really extremely compact and lightweight. Cons: At least on my (rather large) head finds the glasses hardly stop. The small arms are heavily bent outward and the glasses slip immediately from the nose when something prevents upside down what you yes now reading times likes to do. By the way the whole thing looks very weird face. Conclusion: For me, really just a stopgap measure. I use the glasses only occasionally as a magnifying glass, as I consider them without folding the strap just before your eyes. This works really well, the straps are designed so that they do not interfere with a clear view.
