Premium Replacement for Hewlett Packard 51640A (HP 40 Black) Ink Cartridge

Nice to be able get this cartridge at a reasonable price. Occasionally there can be problems with remanufactured products and initially my first order didn't work but I think I got the replacement within two days. That's pretty awesome service. Thanks.

After installing the remanufactured cartridge the first two pages printed looked OK. After that the print quality was beginning to look so poor you couldn't even read it. Would not recommend this cartridge.

quick and easy
