    As the cartridge did not work for me as it should, and after trying the recommended fixes given to me from CompAndSave, I requested a refund and received it. The fellow I had emails from was very patient and kind to me. Thank you for such gracious service. Cathy

    I could no longer find ink cartridges for my old HP printer. I found this site. Received the ink in a timely manner. The ink is just as good or better than HP's.

    I experienced a problem with my ink cartridge not performing as it should. One email to the Combo Ink and I was given directions on returning the product for a complete replacement, at virtually not cost to me.

    HP is known for charging outlandish prices for their replacement printer cartridges. This last color cartridge for a DeskJet 960c lasted fully four months. Comboink's was very reasonable. I recommend Comboink to everybody.

    The color was off from the beginning. Mostly brown and greens no blues etc. I will never go the cheap route with ink cartridge. Don't waste your money. Very disappointed.

    THE price is right and the wait is short. Save a LOT of $$$ over you local box store. Easy to get a couple for the shelf as backups in case the ink printer goes dry. NOTE: Be sure to update your hardware drivers.
