Review on 🖨️ Ink E-Sale Brother TN221 TN225 Toner Cartridge Replacement (KCMY, 4-Pack) - Compatible with HL3170CDW HL-3170CDW, HL3140CW HL3180CDW, MFC9130CW MFC9330CDW MFC9340CDW by Joshua Flame

I was very skeptical but they worked great and I've been using black for a month now and I've even been able to extend the life of the color MFG cartridges. replace it by inserting a new one from INK and letting the machine restart, then sending the old, presumably used, cartridge back to the manufacturer. I've always suspected I wasn't getting the full performance from MFG cartridges, but have never been able to figure out how to override the system. Now I think I can get more prints out of cartridges and save a bunch of bucks. I had to replace quarterly even though I knew I wasn't printing much in some quarters. As for the durability of these cartridges, I need to upgrade them, but I figured that even if they're a little inferior to the MFG, they're so much cheaper that I'm sure it's worth it. The machine is MFC-9340CDW and was purchased in 2014. Since the warranty was long overdue I found out what the heck and the seller backed their product with a warranty so I figured I had nothing to lose.
