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

I bought it for home use and installed the first cartridge in September. Four months later it was clearly out of ink and will need to be replaced soon. Typically a cartridge lasts 6 months and I've printed less in the past few months so shouldn't run out anytime soon. I noticed that the description on the website doesn't claim to be the number of pages a cartridge will print. I don't know how many pages I got from the first cassette as I don't keep track, but definitely not 2000+ like the other reviewer. Maybe the next cartridge will give better results. But even if it only prints 1,000 pages, it's still a good deal price-wise. (I paid less than what is currently being sold.) Haven't tried the drum yet so don't know how well it works. Apart from fewer copies than expected, it seems to be working fine. UPDATE: It's been six months since my first review. I have now "used up" all three cartridges. I put "used" in quotes because only the first cartridge worked. The second two left streaks and bald patches despite reinstalling, shaking, and even reading my brother's owner's manual. Install new drum - no improvement. I bought another company's ink and as if by magic I have nice pages again, so this is definitely not my printer. And it wasn't the operator's fault because the ink was stored properly and I have years of experience replacing toner cartridges. Verdict: Either the rave reviews are fake, or the quality of the product is extremely inconsistent. I have downgraded my previous rating from 3 stars to 1. I would recommend avoiding this brand.
