've Always used for my Epson T2631 only the original cartridges from Epson. But since I have a lot of printing at home, it is very expensive in the long run if you always choose the expensive Epson cartridges. So have now for the first time this so-called replacement cartridges ordered for significantly less money, and I am totally satisfied. A contrast to the other cartridges I have not found. Have you used easily and they were accepted and immediately recognized by the printer. Already I could print and the quality is excellent.
