I sometimes get nervous when ordering 3rd party laser cartridges that are MUCH less expensive than the OEM versions, but I decided to give this cartridge a try for my wife's Cannon printer. Much to my delight, the 2 pack of cartridges arrived quickly (the one in her printer had totally stopped printing, so I was under the gun). The cartridge installed normally and provides a good dark, sharp image equivalent to the OEM cartridge that had been in the printer previously. My wife has had the unit working now for several months with no complaints, and that makes me very happy.
