NOOOOOOOOOO! Do a little search on here for recent Oakley HQ tunes. You'll see how the quality of service has declined. If they **** them up, you'll get 25% off a new pair of glasses in return and they will keep your frame. @THE X-MAN is the resident tune up guy. He can make them better than new, just tell him if you want them factory tight, or tighter. He can do both. He's done 4 for me and TONS more for other members. They are MUCH safer in his hands. Message him about it, fill out the form at http://thexmancustoms.com/ It may take a minute for him to get back to you, he's an in demand guy. But it's worth the wait and the peace of mind.I know I bought these a long time ago. I just couldn't remember when. I think I'm gonna send these into Oakley and let them do the tune up on them.
