Review on GREENBOX Remanufactured Ink Cartridge Replacement HP 60XL 60 XL for Photosmart C4680 D110 Deskjet D1660 D2530 D2680 F2430 F4210 (2 Black) by Kevin Griffin

No problem - read a few reviews and I've cycled them to swap them out and have a nice restart on cart. The ink is a little grey, not black, but I can live with that. Some of my highlighters smudge, some don't. I'm using it for high school. No business. Maybe you want to expand it for business and need some color to look good. Life expectancy is currently unknown.
