Review on 🖨️ V4ink 2-Pack Compatible Toner Cartridge Replacement for Canon 104 CRG-104 FX-9 FX-10 Ink Cartridge for Canon Imageclass D420 D450 D480 MF4150 MF4350D MF4270 MF4370DN MF4380DN Printer by David Vargas

Based on first impressions I was willing to give this product 5 stars. I've only tried one of two packs so far. Installation was easy, fit is perfect, printing on paper is flawless. Then I tried to print a sheet of transparent stickers with a return address (Avery 15695). The adhesion of the toner on this label material is poor and the labels smear easily. Basically, I can erase the label simply by rubbing it with my fingertip. I have no complaints about this toner on paper, but it's useless on tracing paper. I've never had this problem with original Canon toner. UPDATE: Two days after posting the above review, I received an email from someone at V4INK offering to send me a replacement cartridge to try out. I told them to send it in and that I would try a new one on the same transparent label and post my honest review. I had a new cartridge a few days later and it works great on transparencies with no smearing. Based on their customer service and the performance of the replacement toner, I'm increasing my rating from 3 stars to 5 stars. I guess there's a chance someone else might get the same toner, which disappointed me at first, but I'm now completely satisfied and am changing my rating to reflect that.
