Do not purchase. - Serengeti PolarMax Nimbus Polarized Sunglasses with PolarMax Drivers Lenses 6850

This was the 2nd pair of the same glasses I purchased in 2 months. Both pair failed in exactly the same way. The screws holding the lenses to the frame were stripped on both pair. This is a defective product.
Pros: Loved the design & transition lenses.
Cons: Screws holding the lenses to the frame were stripped
