    Works perfectly and a great price. So glad I can still find reasonably priced ink for my older DeskJet.

    Our Company prints hundreds of packets weekly. We started using ComboInk last month by purchasing around 15 cartridges. One cartridge blew out for no apparent reason but ComboInk stood by their product and sent a replacement cartridge swiftly. We plan to continue using ComboInk to save a remarkable amount of money.

    The ink cartridge works perfectly. The color is very dark, just as we had hoped. I will be ordering a combo pack of the black and colored ink cartridges shortly. Extremely satisfied with the product.
