Pros: none

Cons: am doing heavy ink use printing. starter cartridge that came w/ brother 2270dw printed 150pp (clerk at store predicted 700). this rosewill tn450 printed 60pp (out of a predicted 2600). had this performed as well as the brother starter cartridge, i would have expected at least 600pp. when i installed new rosewill cartridge, i rocked it side to side & cleaned corona wire as instructed. Very disappointed. Unacceptable product.
