very good pointI would say so - billet aluminum with cut "CRG" in them, glass is replaceable if you break the mirror only - and it is held in with this small screw and a rubber grommet. Vibes pose no issues that I ever encountered - they were far superior to the stock mirrors.
My ONLY complaint - bar end mirrors require that you take you eyes off the road in front of you. A couple of times I looked down and when I looked up, traffic was stopped in front of me! Thank goodness for quick reflexes!
