I have tried so far, although only the cartridge magenta (the delivery was carried out reliably and accurately to the point where I needed a new replacement cartridge), but this actually worked exactly as described as if it were an original cartridge. The cartridges are all transparent so you can even without software query reliably detect how much ink is still in the cartridges. And: All cartridges are really brimming!
Surprised I had me first about the fact that the connections are glued. This tape does not have to and you should not tear too. They are pierced automatically when inserted and any leaks are avoided. A guide or notice from the manufacturer to would have been nice.
Conclusion: With me so far everything shipshape! I can recommend both the dealer and the cartridges at least for the above printer fully! :-)
