Pros: *Inexpensive *Looks just like the original cartridge

Cons: *Poor Quality. *Gear system extremely stiff, can strip drum unit gears. The toner cartridge's gear system immediately began chattering against the gears of the drum unit. Got black horizontal streaks that are darker with the amount of chatter. Put back in original cartridge, no problem. With the Rosewill RTCG-TN70, only got 1 or 2 clean prints, and that only after fiddling with it to really seat it hard against the drum unit and shimming it with a folded paper, but that didn't last long. Also tried turning the gears manually on the cartridge to loosen it up, and was unable to. The original cartridge turns fine.

Overall Review: I guess paying a third of the price of another cartridge doesn't save anything when it just doesn't work, and can damage your drum unit.
