I then came across this product and bought it because of the mainly good reviews - but to cherish without great expectations.
Delivery took place thanks to Amazon shipping within one business day, and the cartridges are each individually vacuum wrapped, by pointing out that you can store for 2 years. For the price absolutely fine.
In enclosed instructions should be available at the first change every cartridge change (Weil otherwise could cause problems) - so done, wait until the printer has completed the detection and ... lo and behold, 1. Surprise: Contrary to my expectation even works the level indicator all cartridges properly. Then first made nozzle check - black had problems -> 2x printhead cleaning done -> works - then still a precaution calibration run (above the manufacturer in a review comment) and then made a few test prints:
TEXT: Here I could not find problems or differences to the original. Very good.
PHOTOGRAPHY: I have a photo that I have already printed with original ink, now with this ink printed (same paper), and the result ensured the 2nd surprise: You can not really make a difference ... I then extra-outs of both Photos scanned to see it exactly, and the only thing I noticed (at 9600 dpi), was that the Epson ink a bit brighter appeared (Must to say is that I do not know exactly under what color optimization parameters, of which Epson yes some offers, I have that printed 1. Photo - making it also could possibly be due) - in any case you have to look closely at a very damits ever notice.
CONCLUSION:
Even if this ink has a minimal lower luminosity than the original (can someone a "more scientific" make test - just tell me;)), so that, given the fact that you pay 80% less more than bearable. Especially as the level indicator works, which is not necessarily the norm in this price segment is otherwise, and I could find absolutely no problems otherwise.
The only thing that could be improved, in my view, the guidance is not clear from that you should remove the labels carefully before the cap to prevent ink splashes (writes manufacturers here already in a comment). The fact that the ink changes, just with "alternative ink" should not harm his Sunday clothes, actually goes without saying - have so also nothing "eingesaut" me.
Overall: Great value for money -> 5 Stars
