I have purchased these multiple times, and now also reviewed them twice. They are working perfectly, no issues, no clogging, good colour. For the most part, this is what I'm running for ink now. I wanted to add a detail that I missed last time I reviewed this ink. One of the other reviewers noted that the chips don't register the ink levels. This is true on the printer LCD (they always stay max level), but if you install and open up the EPSON Status Monitor it will show you the current levels of ink in the cartridge which will help you regulate the remaining ink. I use Flexi for a RIP, but use the ESM for monitoring my ink levels, works good.

I had no problems setting this up with my computer. My prints are coming out perfectly

So far so good. The only thing that I've seen a little negative so far has been the fact that the printer does not recognize the chip but allows it to be used. Unfortunately there is no ink level feedback so you'll have to keep an eye on it manually. The other side of this is the color stability overtime. But for the price I'm up and running!

Works great. Can't beat the price.

très bien.

So far so good! Quite happy with the results and product. I'm running this in a SP7800 and to be honest, I don't notice any difference in the colour quality at all. As a note, I flushed the lines before I started using these inks, so I know its colour output is all coming from this ink. I use my SP7800 for high gloss photos, production posters and the odd (gloss) canvas (I usually use my HP Z3100 for canvas instead of changing to matte inks) in a home based print/art shop using flexi rip.
