E-Z Ink(Remanufactured Ink Cartridge Replacement for Epson 126 T126 to use with Workforce 435 520 545 635 645 WF-3520 WF-3530 WF-3540 WF-7010 WF-7510 (6 Black,2 Cyan,2 Magenta,2 Yellow) 12 Pack

Pre-purchased this sink on a regular basis, and I’ve been very satisfied with the quality of the ink and how the colors print on paper

This was the first time I took a shot at ordering non Epson ink, and I'm glad I did! My specific printer requires very frequent head cleaning, which uses up a bunch of ink. I don't print a lot, but I run out of ink pretty quickly.So far I haven't had any issues with the printer not recognizing the ink cartridges or with the print quality being bad. It was definitely worth the purchase considering how many cartridges I got for the price, and I can't tell any difference in how my printer works.

These are a good as tne manufacturers' cartridge. Since I infrequently use my printer they tend to dry out, but I'm told the new refillable ink printers have the same problem.

Works well in my printer.

Great product at a fair price.

I was not having issues for awhile, until today..Today I needed to replace my black ink, and I went thru not, but two ink cartridges SO FAR...It has taken over an hour of my time that I did not even have, troubleshooting through head cleanings, nozzle checks, etc, to finally just say "well, I guess I better open another package"....uugh. I needed that time to be finishing my homework, not messing with my printer. Lesson learned.A month or so later...SAME. Printer telling me it does not recognize the cartridge MID-PRINTING. The same cartridge that has been working fine. So, pulling out yet another cartridge. Lowering rating another star.UPDATE: if I could give zero stars, I would. The previous "a month or so later" paragraph was from just a few weeks ago. Now my printer says that the black is full, but I am only getting part of a top line and then faded to gray. Yes, I have cleaned the printer heads (twice) and done nozzle checks, etc. And by the way, when I first wrote this review and said "not having issues for awhile", the implication was that there had been issues before...and there had been, certainly. But not enough to say, "oh, this discount ink is junk"....but now I see that it really is too much of a gamble. Sadly, since I bought this huge pack, which means it does take awhile to use up, I am way past the refund window. So, my only option is to come back here and warn others. It really is a gamble. So, I guess I am pulling out YET ANOTHER CARTRIDGE and putting in yet another new one (from this company), hoping that it works. I am a full-time college student who is also working part-time and running a household (grown-up, 2nd bachelor's degree, so it is not as simple as the first time), so I am most definitely on a budget, both with my money and my time. This kind of frustration is not welcome. If you have time and money to waste, buy these cartridges, if like me, you don't, I would find something else.Another update, Spring 2023- suddenly my printer does not recognize the blue ink cartridge that has been working fine. I don't have any more blue, so I have to order more. I would just give up, but I still have other full cartridges, and I am not made of money.

I print a great deal from two Epson Workforce 645 printers for the classes I teach part time. At nearly $20 per cartridge from Epson the ink costs were killing me. I started using the Remanufactured cartridges. They are not perfect. There tends to be some streaking which can be corrected with a head cleaning. I have learned to make a light swab with a q tip over the cartridge head before I insert the cartridge. Then just automatically do a head clean after the insert. They work fine after that. Lots of users are complaining about having to answer a warning message about using non-recommended cartridges. These people are the type that can't handle anything out of the routine. It is true that the additional work to get the cartridge working makes them less convenient than the expensive Epson cartridges. But the cost savings is HUGE. And Office Depot will give you $2 for each spent cartridge, which is more than it cost to buy them in the first place! If you do a lot of printing you can't afford not to use these cartridges.

I've purchased these exact cartridges in the past but this latest box has nothing but problems. The printer will recognize and then days later say "unrecognized" and will not print prompting to install a new cartridge. Wasting ink and cartridges trying to reconcile. It's a known problem for the manufacturer... they even have a message printed on the side of the cartridges telling you if you get this warning to try reinstalling 2-3 times. And then to contact tech support. They know they are junk.
