I was late in writing this review as I was waiting for at least one cartridge to be fitted. To date, the black cartridge produces dark, rich black levels, just like the original cartridge before it was "extremely low" according to the printer. Can't comment on other colors yet as they haven't yet been installed, and I can't comment on durability either. I didn't give a 5 star rating just because the box arrived with a corner chipped off - not due to mishandling during shipping, but because the glue used to assemble it failed. I have contacted the seller about this but have not received a response. - - - Fast forward a few months and now I've set all the colors. They work well although I started bruising on each side. I took out the cyan cartridge and found cyan toner stuck to the roller next to the drum. I removed everything with a cotton swab and I have good clean prints again. I have noticed that all of the colors bleed a bit around the moving parts of the cartridges. But for a quarter of the cost of an Original HP all 4 color cartridge, I won't complain too loudly. Another month or so and the cyan cartridge will color every page again. I will clean it again and most likely will not buy replacement cartridges of that particular brand again. I'm deducting one star for the second performance of the leak - - - Another month and now the leaked blue cartridge is impossible to fix. I cannot recommend these cartridges at the moment.
