These are by far the best value in a black cartridge taking a canon 128A cartridge. The cartridges are a fraction of the price and the print quality is excellent. They are shipped out quickly and on the rare case a toner is defective, 123ink.ca replaces it promptly and without charge. It cannot get much better than that

These eco-saver black toners are awesome. I am currently running three (3) Canon printers, one of which is the Canon ImageClass MF4770n. Just like the inkjet printers these toners are reliable affordable and never let me down. The shipping from Shopper + is quick. Thanks again.

works great and reasonably priced

Does the job

I buy these six packs constantly. I have had one bad toner out of over 100 purchases, which was quickly replaced by 123ink.ca. I will be buying another six pack in the very near future. Thanks agian.

Exceptional product, at an exceptional price for a six pack. Always shipped on a timely basis and always in stock when I order. I have three printers that use this toner and their has never been a problem with this brand of toner. Thank you 123Ink and Shopper +.
