I'm not sure if these are legit gascans or not. My main concern is that one of the armstems(right) does't lock into place and when I got them the hinges were squeaky. Also, left earstem does not have oakley icon printed inside. Only the right earstem does. (See pics below) Matte Black w/ polarized black iridium lenses? On my other pair(which are real), the serial is printed on the right arm rather than the left.
