Has anyone used this from some of the older batches say QVE-004 they expire in oct of 2004 compared to the newer stuff that expires in 2006. Any ways the gear that expires in 2006 has a stamped expiry date while the 2004 has a printed on one. The holograms are both the same an immaculate (nice holos). Do you think that the older batch had a printed on expiry date and when counterfeits arose they started to stamp the dates? or did i get some questionable gear?
