I had purchased 4 901XL replacements cartridges fro 1ink.com, 2 worked ok but not great, the 3rd and 4th cartridges did not print at all. After insisting they refund my money they gave me a return Authorization #. I send the two cartridges back to them and never heard back. I called today and gave them the Return Auth. # and they said both returned cartridges were empty and therefore they were doing nothing. I had cut the plastic bags off them prior to use. I recommend not using them. read full review »
