I use the set in a HP B110a and am satisfied with the print results very. Even the level indicator works fine! The installation went quite easily by hand, you must only confirm the message from the printer, which you have no original HP cartridges installed and can then already started. After installation, I have automatic printhead calibration carried out and connect can print a print quality report to me. Here they even give the expiry date of the cartridge shown and the PHA Drop Test shows values similar to the original product.
A small tip for using the black cartridge I want to give at this point even further: When removing the orange seal should not hold the cartridge too tightly and thus squeeze, because it can happen very quickly otherwise that emerges from the opening ink !
Given the fact that the cartridges with more content not even cost half the original cartridges and there is no obvious difference in quality in the print result, a strong buy recommendation.
