Big Print Outs Look Great With Epson Ink
Style: Cartridge Ink
So I paint and I'd been trying to find a way to print out large pics to aid me when I'm trying to get my shading correct. This ink is fabulous...the printer just does a great job. First I print one in color and the second in greyscale...it helps a great deal when working with the shading. Epson can even add a couple other color cartridges to get different effects. I'm very happy with Epson inks. They really made a good selection of colors to make prints look amazing. 5 stars

Great Color
Size: 1 Count (Pack of 1), Style: Cartridge Ink
I was hesitant on purchasing this item. My skepticism was relieved when I installed and printed the first picture...very good quality. However, seems like the ink supply went quickly, either not a complete cartridge or I print too much(which I don't).

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.
