Review on E-Z Ink (TM) Compatible Toner Cartridge Replacement for Canon 128 CRG128 3500B001AA, for Enhanced Performance with ImageClass D530 (Black, 2 Pack) by David Will

product arrived on time and the printer had no problem recognizing the cartridge (i had a problem with a competitor) i don't think the page is as dark as the oem on the 600 but at 10% off the OEM price I find the print dark enough for what I print. I could make it darker by cranking it up to 1200 but the toner runs out quicker. I found the product more than met my needs at this price point.
