Review on E-Z Ink (TM) Remanufactured Ink Cartridge Replacement for Epson 127 T127 (12 Pack): Compatible with NX530 NX625 WF-3520 WF-3530 WF-3540 WF-7010 WF-7510 WF-7520 545 645 - 6 Black, 2 Cyan, 2 Magenta, 2 Yellow by Gregory Shorunov

I have an Epson WF3540 series printer and my husband bought this ink cartridge from another manufacturer. I installed it and got a warning that it was a third party cartridge which could affect my print quality. I went ahead and proceeded to install the cartridge. I had several things to print and they were all done with "new" black ink. I even cleaned the printheads after the bad results and you will see in the picture above that this didn't solve the problem. All my other Epson inks are good, but the black EZ inks are not. I miss the return window and have four more cartridges with stuff that doesn't fit at all!
