    Received cartridges in a timely manner. when getting ready to install three of the four cartridges had leaked some ink into the packages that held them. I still installed them because the loss was minimal. \ I will use combo ink again unless bigger issues happen.

    I could not get the cartridge to work so I made a 10 mile trip to WalMart at dark-thirty O'clock for a HP cartridge at double the price plus the gas to get there and back. I had no trouble with the HP brand.
