They work exactly as described.  My only(minor) complaint is that they are a bit rigid and don't lay down on my neck.  They stick out and when I'm driving, they hit the headrest when I turn my head.  I'm in my car all day and it has taken a bit to get used to them.  Minor issue, just be educated before you buy.  Well built and designed.  Fit both Oakley Turbine and Smith Elite Tactical sunglasses.
