Hey guys and gals I'm trying to figure out how you can tell the difference between a real v3 sentinel from a fake.i know they started copying the engraving and the silver coated contacts,so its really hard to tell now a days.i did a trade and want to know if its real or not.my trade was real so I would expect the same.can anyone take their's apart and show me the contacts? Would really appreciate it,also any info to would be great.thanks in advance.
