I use since about 5 years only these cartridges and agree to the print result, mainly photo prints up to A4, on Photo Paper Pro, very satisfied. The colors are clear and rich in contrast, the ink dries very quickly, so that there is no blurring. Also documents on different paper are properly. The adapter, once properly installed has yet made any problems, although it is the first still and have already taken place many cartridge changes. In order to assess the yield of the cartridges correctly, the me compared to other brands and printers lack. The consumption will of course depend on the particular use, which outweigh the color photos with me. The large cartridge with the black ink for documents has never dried out or otherwise failed by prolonged disuse. As long as I will not let the printer down, for me there is no alternative to the ARMOR cartridges.
