This is my second pair and Ill probably buy them again.  The only reason for the four stars is the fact that they are not very robust.  I didn't see that they had fallen from my pocket as I was getting into the car and started to sit on them.  They didn't bend.  They broke.  I love how they wrap my face and protect my eyes from sun from the side.  I also enjoy the clarity of the optics and the magnification.  They are great driving sunglasses.
