WOEBYAS 121 Black Toner Cartridge Compatible Replacement for Canon 121 CRG121 CRG-121 High Yield Replacement Work for Canon imageCLASS D1620 D1650 1620 1650 Printer (Black, 2 Pack)

Perfect fit, no issues. Significantly cheaper than brand name.

Was afraid to try these since I've had bad luck with generic toners for this printer in the past. I had to spend over a hundred for the OEM product. But I'm surprised that these perform so well. Very rich black color, no gaps or smudges. i'd buy it again.

I switched to this compatible Canon 121 black toner cartridge recently and am very happy with it. It fits perfectly in my printer and installs easily. The print quality is clear and sharp, almost like the original Canon cartridge. I’ve printed hundreds of pages with no smudges or jams. It saves me a lot of money compared to OEM cartridges without sacrificing quality.

Surprised, yes, but in a good way, has worked well, thanks for a superior product

This toner works very well with my Canon 1600. One of the cartridges was busted, and I didn't notice it for a while, but I was able to get a replacement. Very pleased with this!
