I'm not at all satisfied with an ink cartridge EPSON T1801 Daisy 18 Black Ink I bought in late November 2013. In fact, currently, one of the two received cartridges did not have a duration of life as those I've used, and from another store or service provider. I could, however, print sheets in a week, with normal consumption and not excessive, the cartridge was empty ... I saw the cartridge refill indicator was emptying quickly ... She comes from a faulty batch ??? or is this a hidden defect ??? I do not advise this, or at least it may be necessary to review the provenance of the product ...
