Lightning-fast shipping and great packaging
Lightning-fast shipping and great packaging (return label was included). The quality of the Serengeti lenses is immediately apparent: impressive clarity and zero glare. They offer excellent sun protection, although the photochromic transition is very subtle and barely noticeable. One note of caution: the fit is quite narrow. The spring hinges flex to accommodate and are comfortable, but I am concerned that the tension might stress the frame over time. Overall, however, I am very satisfied so far.
