Review on Leize Compatible Toner Cartridge Replacement for Canon 057 057H - Black 3,100 Pages, 1-Pack - Perfect for imageCLASS MF445dw, LBP226dw, MF448dw, MF449dw, LBP227dw, LBP228dw Printers by Keith Stuckey

Directly on the packaging it is clearly stated that there is no chip that does not correspond to the name of the product, where "CHIP" is clearly written. It's disappointing that you don't get what you pay for. As for the product itself, I have not used it yet as the original toner has not yet run out.
