Review on 🖨️ E-Z Ink (TM) Remanufactured Ink Cartridge Set for Epson 212XL T212XL 212 XL T212 - Compatible with XP-4100 XP-4105 WF-2830 WF-2850 Printers (1 Black, 1 Cyan, 1 Magenta, 1 Yellow, 4 Pack) by Matthew Allen

This is the second 3rd party brand of ink I have purchased and the first that has worked well and consistently. Another purchase I made was a big failure and I had to go back to buying branded ink which is way overpriced. This product included instructions on how to roll back the firmware on my Epson WF 2830. Detection problem. They work perfectly. The problem is solved! Yes, the Epson software offers to update the firmware. As far as I can tell, this is only to prevent the use of these third-party cartridges (which are reasonably priced). I will continue to order these inks! The print quality compared to my Epson brand ink is basically the same. I see no difference. Affordable, reliable purchase, will buy again! A little bit of my story for those who are interested or might benefit from this: I used to have HP printers, but a tri-color cartridge, when empty in only one color, wouldn't even print (not even black and white). Sometimes it's a waste of time and money. I tried Brother for a while and had decent success. I liked that the colors were separate cartridges and you only had to replace what you use. Unbranded inks were available and inexpensive BUT the print quality was airy and light, not as vivid whether it was Brother branded or non-branded inks. After my brother's printer finally died, I was impressed with the Epson WF series printers/scanners and their cost. Original purchase and ink worked very well. But Epson ink cartridges are too expensive. I tried another manufacturer's inks and found they didn't work with my printer. No bueno. The network says that this is the firmware. Maybe. Anyhow, this product came with instructions on how to uninstall Epson firmware updates. Not sure if this was a problem before or if they're just better made, but they worked in the snap with no issues. At this price I'm happy to find something I can count on.
