50/50 - one worked great, the other not so great
Reviewed in the United States on August 22, 2014
Toner package came quickly and the print quality is OEM. My only complaint is that the printer is flashing the error light and shows a "Check toner cartridge" error message. I used replacement cartridges from another vendor in the past that did not cause the error. I don't know if this will affect the functionality of the printer. So far after a hundred pages the print quality has been consistent. I did not open the other cartridge to see if it also causes the error light.
UPDATE: 8/26/14: I removed the orange protective clip around the two electrical contacts and the error light went away. I have the installation directions in front of me now and there is no mention of removing the clip.
UPDATE: 11/21/15: I got 1300 good pages out of the first cartridge. before the printer started reporting Toner Low. I was able to keep using it for another 200 pages without any noticeable page quality changes, so it was good for 1500 pages.
UPDATE: 12/26/15: The second cartridge is leaving a series of smudges on every printed page. When I inspected the cartridge there is a streak of toner that is on the green roller. It is easy to clean off but it gets redeposited on the roller in the same place.
