I've been a long time fan of Ray Ban, but over time I find them too heavy for my taste. Sure the overall quality of Ray Bans are of a higher standard than Mariener, but for the money these are excellent sunglasses to throw around and keep them in the car, which is something I would never do with my pair of ray bans.
Shipping is fast, customer support is friendly and goes out of their way to help you if you have any issues (I had a small scratch on the frame due to transport).
