Review on 🖨️ INK E-SALE Dell 525 E525 E525W Compatible Toner Cartridge Replacement (KCMY, 4 Packs), for Dell E525W Color Laser Printer by John Eaton

We have used all 4 cartridges and had a very mixed experience. Two cartridges worked properly (yellow, cyan). We have had very bad experiences with the black magenta cartridge. The black cartridge became invalid when Dell released a firmware update for the printer. We had only been using it for 2 weeks when this happened. Before that, black worked well. But once the firmware was installed, it immediately stopped working and gave an error message until replaced. We just added purple three days ago. After printing about 100 pages, the printer tells us that the cartridge is empty and needs to be replaced. Print quality has never been an issue. The prints looked great. And the two cartridges that still work are fine. But if you only get a very limited number of pages from a cartridge and the question is which ones, I can't wholeheartedly recommend it.
