I had bad luck with a Brothers replacement cartridge which only printed about 250 pages before it began to have smudges on the printed documents. It was a $95 cartridge and I didn’t want to throw it away. I tried everything the manufacturer recommended to solve the issue with no success. As a last resort, I bought this cartridge for $25 and it solved my problem!! So far the cheap $25 refill works better than the $95 Brothers cartridge.

I was hesitant about using non original toner having heard too many stories about how they never work. I took a chance having read the reviews. I can now say that at least for this toner it works great. I cannot tell the difference in quality at all. The pages are as crisp as ever and the price much cheaper that the originals. I wil continue to use this product for sure.

I bought this ink on a good sale and thought I would give it a shot. It works great, no issues, easy to install. The printer tells you its not genuine ink, but it other wise works fine.

Overall impressed with cost and quality. Always hesitant to try non OEM products but this was so much more affordable, thought it worth a shot and glad I did. Easy to install, chip connected fine and after three months print quality remains excellent

Original Brother black toner that came with printer was leaking; this replacement worked on my MFC-L3770CDW without issue and is printing well so far
