All metal frames are a bit "off." Also, all metal frame sunglasses will eventually be sat upon, just like all sunglasses with plastic lenses will get scratched.
This doesn't matter of course since all sunglasses are made by Luxottica. They all come from the same place.
And even Randolph now brands their sunglasses, though you can scrape it off with an exacto. Of course you will end up sitting on them shortly after you realize this.
Giving up on sunglasses prompted me to give up on contacts. Prescription glasses with quality frames (prodesign, japanese brands, Persol, etc) and transitions lenses are essentially loss-proof sunglasses.
