Wired Magazine Article On Oakleys And X Metals In Particular

[i'm broke now]

In response to BriP's post, I would point out that I bought my R1s from new way back, and never knew that there were apparent stress crack issues with that model until I read about it online.
I just treated my £250 sunglasses with due care. Mine are still perfect.

Ditto, mine are 12+ years old with many years of daily use and didn't hear about the stress cracks until I read about it in for sale posts and ebay auctions.
