Review on v4ink Compatible Toner Cartridge and Drum Unit Replacement for 🖨️ Brother TN450 TN420 DR420 - 4 Packs (1 Drum 3 Toner) (Black) by Wyteboi Nallamothu

I have been using this brand of ink for over 8 years and have been completely satisfied with it until recently. My last 2 purchases (4 toner cartridges at a time) have been a total disappointment. They smear, print too light, stop printing long before they should. Only the quality has gotten worse. I switched to a different brand of toner this year and have used it on the same printer with no problems, proving to me it was definitely the ink and not the printer. would i buy again this brand of toner? No longer.
