Don't be fooled, these are not the old serengeti quality. I know because I've bought 6 pairs of serengeti's. The nose pieces are flimsy and pressed together and the glass has a poor frame fit. Perhaps some of the other older styles are better...
Pros: Good optics
Cons: Trash frames - Weak nose piece, poor glass to frame fit
