I have the printed pages not numbered, but it was definitely more than the original toner! And for less money ...
The quality is also very good. Although Printed photographs are not the same quality as with professional printers. But that can also not afford the printer (CLP 320). The toner, however, does not run, dries quickly and provides a sharp image.
After I was disappointed at the first attempt with a Rebuild toner I have ordered this here as a "last attempt" again. And will stick to it!
Conclusion: (! And the color) Both of these black toner deliver a super result that the original toner at least very close to coming. I as a layman can recognize at least to the naked eye no difference to the originals. Same performance for less money, keep it up!
