I have used the endura ink in my 1204 since i bought it new. I had one major issue where the cartridge ruptured in the machine. Sw stepped up and took care of the damages except for my flooring. I have switched from endura ink to mutoh and back during printing with zero issues. Color match was identical. For the money id say give it a try. Like i said i had a cartridge rupture and from everyone i talked to about it its a rare occurence but it can happen. I dont think it was anything wrong with the brand. Being a house brand its clearly just relabeled and i wouldnt be surprised if it isnt mutoh inks re labeled for SW since they are such a large dealer and have the 1204 exclusively. Also, it seems as if there is more ink in them. Once the machine starts beeping there seems to be more ink left once i pull it out than there was in the mutoh cartridges. Could just be my imagination tho.
