I bought these ink cartridges. Are a week later gekommen.Der content was properly mur lacked a black print cartridge. Was claimed by me. Was only after the third complaint request an answer. They wanted documents to the delivery. I have added sand by email. After that was just intermission. Thanks to Amazon which was turning on the excess demand money repaid. It should simply be supplied a black cartridge, which has not happened. So you can scare off customers and also as long as the thing to sit out until the customer no longer reports.
