I have this printer Partonen ordered and installed for the first time. They are very accurately and the ink quality is acceptable for normal printing. What I noticed is that cartridges have - like the original - a small plastic front nose to hack in the printhead. Thus, the cartridge is better than many other secondary products. However, the ink tank is approximately 40% smaller than the original (about 7 ml). That you can not bear but, since the cartridges are quite cheap. But because of the smaller ink tank is not declared, there is a star deduction.
