I go through about a pair of lenses a month, most of the after market lenses fit poorly or scratch very easily, these literally fit and look like original Oakley lenses, very happy ill add on to my review after I wear them for a few weeks .
Pros
Just as advertised, haven't found any issues, just as good as OEM
Cons
The BLAZERBUCK lenses may not fit properly in all Oakley Crankshaft frames
