Had some ink cartridges for my DX 5050, mostly also not originals that are just too expensive. Had a couple of times ordered druckerzubehoer.de, best score, more than 1,000 times. For me, they were not accepted. In retrospect, then I noticed that there is indeed a bonus system for the customer when you turn Reviews for items. Accordingly, little then say a thousand good reviews from well :) In this package, there were now black 8x and 4x per magenta, cyan and yellow. All together used fresh, without hesitation recognized, pressure is great. No stripes or so. In other cheap cartridges maybe I could print 3 pages after that I had to make a printhead cleaning because more white stripes could be seen as a color on the printed pages. Not so with this one, everything works perfectly.
