Pretty good, it gives me streaks in some parts of the print (usually in solid areas). The printer of course recognized that it is NOT genuine, nevertheless it works. Update after 5 months: the new black ink I put in does not print

No problems at all! The printer did give me a notification - during installation - that the inks are not genuine, I clicked "OK" and since then it hasn't bothered me again. I've bought them twice so far and I will buy them again.

I tried it at the suggestion of friends who considered me a fool for using genuine ones. Conclusions: The print quality is almost the same as the genuine inks. Their problem lies in the fact that the ink composition is such that it does not dry immediately like the genuine ones. Result: a) You cannot print double-sided in any case because the page will stick 100%, b) in 50% of single prints, the page sticks since it comes out like a wet cloth, and the rollers that guide the page out do not work miracles. The return (unfortunately) to the very expensive genuine inks is a one-way street; otherwise, I will have to throw away my brand new (it hasn't been six months since I bought it) EPSON.

They were recognized immediately and the prints are very good, satisfied also with their price, the genuine ones are very expensive
