Have owned many Serengeti products, but these are likely the best so far. Can't say enough about the quality of the frame, optics, and overall design. However, the lenses are very easy to scratch, and even the slightest impact with a rough surface may be damaging. Very good price at Optics Planet - much less expensive than elsewhere.
Pros: Very light, phenomenally comfortable frame, excellent image quality
Cons: Polycarbonate lens scratches easily
