yeah :/ my other gascans lock solidly. (polished black) These matte black gascans hinges were so squeaky when i got em. They are fine now after i sprayed some oakley lens cleaner in the hinges. I heard this issue is more common with the matte color gas can. However, these are still one of my favorite sunglasses to wear. Even over my polished juliets.

Thanks for the clarification. I have another pair of real gascans(picked em up at optometrist). However, is there any difference in the arm the serial is printed on? I have a pair that are on the left and another pair on the right earstem.

I'm not sure if these are real 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?
