We have for the first time ordered the compatible cartridges for our HP printer and are fully satisfied. From the first to the last page an original print result. The price of the 10 cartridge is super. After inserting the cartridge, the printer complains though, with confirmation that no original HP is in the unit, everything was OK If times a cartridge "spinning" and not print, it is the print head of the unit, align or clean the print head and it prints. We order there again.
