BUBU Bird Compatible Replacement for HP 920XL 920 XL Ink cartridges High Yield Work with HP Officejet 6500 6500A 6000 7000 7500 7500A E709 E710 Printer (1Set+1Black)

At the beginning, HP messages appear indicating that the cartridges are not genuine HP and the color printing is not correct. But after a few days everything works fine. I am satisfied because the price difference is very large.
