This review is based on the color output not on whether the cartridges work. The cartridges do work which isn't always the case with the re-manufactured cartridges. My issue with the cartridges is that the output doesn't come even vaguely close to what I see on screen. With the Epson branded cartridges I got a reasonably similar output on paper comparing to what I saw on the screen. You get what you pay for in most things. I paid under $8.00 for the set, which is less than a single branded Epson 127 cartridge. This is a reasonable purchase if all you care about is black output but if you are looking for color photos I would NOT recommend these cartridges. No printer setting change resulted in better color output. It was all washed out out at any setting but high quality and that was very skewed even using high quality paper.
If reviewing a product, it may have been received free of charge. That will NEVER have a bearing on my recommendations.
