Who the cartridge but uses so as thick stands on the film: "Pull off the yellow label before removing the nozzle cap", ie roughly translates to "remove the yellow label before the cap removed", will experience no smear.
When print quality I can so far see no difference to the original cartridges (ie, the fuel gauge works wonderfully), which I print mainly documents and little pictures.
Conclusion:
Everyone is free, if he wants to remain faithful to the original, or try this alternative. Personally, I have found for me an absolutely convincing alternative and am convinced 100%. The price is unbeatable, and not to complain about the quality. The quick delivery is the last convincing argument for me.
