I've got two ancient Oakley Mumbo/M-Frames (like the ones pictured below).
Both frames snapped recently. The material seems to be pretty brittle after 10 years or more.
I've heard the Oakley warranty approach is pretty legendary replacing things even after so many years.
Is this true from anyone's experience? The warranty card mentions a '1 year' warranty.
What do I have to do to get the frame replaced? I've got an original receipt for at least one of them.
I would understand if they don't replace them. But I don't want to waste my money if they do.
I definitely want to have them again. They are brilliant and I have some lenses to go with them.
