Review on 🖨️ V4ink Compatible Toner Cartridge for Canon 137 - Replacement for imageCLASS MF and LBP Series Printers (2Packs) by Jon Brazil

As a twin pack, one worked better than the other. The one that didn't work so well printed extra lines and notes every few pages. Both perform about the same as branded cartridges and the print quality was about the same. Generally satisfied considering the cost, but if you want to print something that needs to be presented professionally, you'll have to print multiple times with the same cartridge until you get a clean copy of each page with no extra lines. .
