First, I thought; Cool, kind of save the environment and save money. So I ordered these cartridges for my Epson DX7400. The first he has completely unrecognized. The 2 supply was recognized to 3/4 from the printer. Yellow did not go still. The quality of those who went was right mieserabel. The Retoureschein I had better draw than the printer has printed it with these cartridges. AND; After each test, print the contents of the cartridge has been halved, from each color even when I printed only in black! As far as saving on. Then I bought the originals again = Top quality and no problems.
