Have the Stix filled the same, but it takes quite a while so before you see the results, because still is the original color in the printer. The Yellow look slightly different from the original, a little darker. But after I've now used up a few bars of it, I must say that you really can not tell the difference. Have it compared with previous prints that here had. So I'll continue to take only the Colormedia because they are in the good stuff yet convenient. Therefore, from my 5 stars.
