Typically I order enough ink to last a few months.  When I finally installed this cartridge in my printer it would not work.  Upon further examination I verified it was in original "Retail Packaging" but had been expired for many years.  I never thought someone would buy up expired ink cartridges and re-sell them.  DO NOT ORDER FROM ECO whatever.  My discovery that this cartridge had died long before I received it was too late.  I'm not able to request a refund or have it exchanged.  STAY AWAY
