Skeptical, but ... (UPDATE)

Subject remains only say one thing:

There are no problems with these cartridges.
My Epson WF-3520 has recognized and accepted the cartridge.
The print quality is fine. There is no smear, no dropouts or the like.

Delivery takes something but this is because it is made from abroad. Nevertheless, the article came well before the laws appointment.

I forgive SUBJECT five stars because this product corresponds to the original, there were no problems so far and printing costs can be reduced to a minimum immense.
Should this situation change this or should notice something, then I'll make an update here.

Until then there from me a clear and unhesitating buy recommendation.

UPDATE 05/28/13

Meanwhile, three (Black, Cyan, Magenta) Original cartridges empty. The replacement cartridges were used, readily accepted by the printer and the print is still like the original.
