Not sure of the longevity. I have had this cartridge for less than a month, but the print quality is what I was missing from the last companys cartridge replacement. Sharp and dark, not light and lacking contrast. I will chime in about longevity in a month or so, but this is probably my go to cartridge replacement for my Canon MF 229 dw laser.

We love how easy the shipping was and how awesome this cartridge works for our cannon.

I obtained these cartridges for use in my Canon ImageCLASS MF236n. The pricing for this product was excellent. I like that they come in a two-pack, as it was like receiving two cartridges for the price of one.

I ordered these replacement cartridges for my Canon MF247dw printer. The two cartridges come in one box, each wrapped in a thin plastic sealed bag. However, one of bags had a long cut in it.

I have a Canon MF230s series laser printer and this toner set is an exact match for the manufacturers toner cartridge that came with my printer. Easy to install, fit perfectly! I cant speak on the longevity because these toners last pretty much forever and I just installed it, but the ink prints out black and cleanly! No complaints so far.

Great replacement

Works fine, print is dark and sharp, no smudges.

Simple easy install and printing quaility is very good.

This company’s toner works just fine. Sometimes replacement or third party brands don’t fit quite right, or print with bad quality. No issues here. Well packaged, quick delivery, and competitive price for two toner cartridges. Will use them again when I need more!

I cant offer a statement as to longevity because weve just started using it. But for the price compared to the original and that there is nothing different about the prints, Id buy it again.
