Review on Kingjet 970XL 971XL Compatible Ink Cartridge Replacement - Officejet Pro X576dw 🖨️ X451dn X451dw X476dw X476dn X551dw Printers - 4 Pack (Black, Cyan, Magenta, Yellow) by Corey Nyuon

I would buy them again without hesitation. In the past, when I've bought second-hand inkjet inks, they've never been as good as the original inks. They seem pretty close to a perfect copy of OEM performance. I added black and cyan before printing 300 copies of a very blue, thick client brochure. Some of them were printed with OEM inks, some with Kingjet inks and I can't say there is no difference in hue, fill or gradient performance. Make sure to manually update the firmware on your HP printer before using it. This seems to solve many problems for other people. (And the latest firmware solved a crashing problem I was having with some PDFs on my printer.) Initially I had a problem with the cyan cartridge even though my firmware was already up to date. I notified the seller and he sent a new cyan cartridge with no hesitation and no issues. The new cartridge worked great out of the box. Not sure what the problem is. Black installed with no problems. And Magenta installed tonight with no problems. After printing 300 full color double-sided brochures in heavy blue, my HP X476dn estimated that there were 4,800 pages of ink left in the cyan cartridge. The black and magenta cartridges are still so full that there aren't even any reviews yet. just say ok (So according to the manual there are still over 5,000 pages left.) Sometime in the next few weeks I will probably run out of the last yellow OEM cartridge. Then I have 100% Kingjet cartridges in my squad.
