I have been reading your cimpany reviews and it was interesting that the only good review had the name of the writer, is this a relative/friend of a company employee? Just wondering! Anyway, I sent in a bulk (probably around 100 cartridges, sorry I did not count them but there were loads) of used once Epson genuine cartridges purchased from Argos that all failed the test so nothing could be paid. You need to check your testing equipment as either the equipment is dodgy or this company is? Thanks for letting me know that you will dispose of them in a responsible way, next time I will just do this myself and save my self the packaging, trip to the post office etc.
