Review on 🖨️ Samsung CLT-K504S Toner: High Capacity Black Toner for CLP-415NW, CLX-4195FW, SL-C1810W, SL-C1860FW by Glen Needham

I'm apparently 2 days late for my 'return window' - but I ordered this cartridge as a backup, now that I need it I've found it isn't is working . does not work and I have no options. See image. The blue ink page is exactly the same, but see if I print it with black ink. The letters are not all printed. Something MUST be wrong with the cartridge or the blue will not print perfectly. Now I'm stuck with a $70 cartridge that I can't use - complete garbage.
