At first I had just bought a black cartridge, this worked perfectly. Then I bought this set. I am using an HP LaserJet 100 M175nw. After insertion, I realized that one of the color cartridge is leaking and powder on one side runs out when you hold the cartridge at a slight angle. The printer receives the cartridge not properly calibrated, ie the inking of each cartridge is very mixed. The printed image is completely unusable.
The seller Tito-Express I have informed, unfortunately, no reaction took place. Understandably, I would not buy this set again.
