My son purchased these glasses in October 2014 from this seller and when they broke last month, we sent them to Ray-Ban.  I got an email this week from the manufacturer stating these sunglasses were not authentic Ray-Bans and therefore were not covered under warranty.  If you are looking for Ray-Ban look alike glasses (non-authentic glasses) these are fine for the lower than a store price, but if you want the real things, do yourself a favor and purchase from an authorized Ray Ban seller.
