My main gripe is the incredibly bizarre design of the bridge (which allows the lenses to open or close to adjust for the distance between your eyes). I've never been told my eyes are closer together than everyone else's but I can just barely get these things closed enough to get a clear circle of focus. They are definitely designed for people whose eyes are set far apart. Definitly won't work for a kid. In fact, if you think you're 'average' in this regard I'd be sure to check them out in a retail store before you buy them - just to make sure they will fit.
Pros: Great bang for the buck ! Very clear, crisp and sharp focus. Excellent for those for wear glasses.
Cons: Design of bridge, a little heavy
