Review on COLORETTO Remanufactured Printer Ink Cartridge Replacement for HP 60XL - C4680 D110 D2680 D1660 D2530 F2430 F4210 (2 Black) Combo Pack: High-Quality Ink Solution by Ryan Cross

My husband bought it and I was very skeptical. One of the few times I've been wrong. This ink is the same as the HP printing ink I buy for our printer but at half the price. The only thing is that my printer prints much slower with this ink than with HP inks. I had to change the print settings to the lowest quality, otherwise it would take more than a minute to print side A. Still good ink and unbeatable price. I'm not sure if you need this if you're printing in bulk, but I also have an old printer so it might be.
