Good quality
Size: 1 Count (Pack of 1), Style: Cartridge Ink
I would say great value, but I can buy it for the same price in store. I think it’s more of convenience to be able to get it without having to go out.

Good quality, although expensive
Size: 1 Count (Pack of 1), Style: Cartridge Ink
Frankly, as with other printers, I thought that I could use reconditioned cartridges with this printer. The first set I purchased was not recognized, thus I have had to purchase genuine products. The cartridges, also offering good color, do not last long. It's a trade-off between cost and quality.
