Review on MIROO Compatible Toner Cartridge for Samsung MLT-D101S - 2 Black Pack"| "High-quality Replacement Toner Cartridge for Samsung MLT-D101S by MIROO"| "MIROO Compatible Toner Cartridge for Samsung Printer - Black (2 Pack MLT-D101S) by Joel Wright

Delivery corresponds to the description. I bought them in January but I hardly ever use the printer. I installed and the 1st cartridge worked fine. I typed maybe 5 times between January and May. Now I go to print and it doesn't work because I get a message that the toner cartridge is missing. I opened another cartridge and I get the same thing. NO TONER CARTRIDGE. And of course you can't return it.
