Useless! 13

At the very opening of the orange plastic security felt a surge of black ink against which now adorns my right middle finger.
The inserting into the printer working properly, however, and the printer recognizing the cartridge although not as original products but the level indicator and the first test print still functioned flawlessly!
However, the second attempt a Word document to print from the pure text consisted passages, only illegible lines came out of my HP printer. All attempts failed to achieve a usable print result!
Since my black HP original cartridge previously used was unfortunately run out completely, it turned the printing of the return label as a real challenge ... which lies be solved only after receipt of the original HP cartridge!

Conclusion: The cartridges are absolutely useless and rather than the hoped-for savings obtained nothing but frustration and dirty fingers with ink !!!
