Genuine brother product with good price

Fast Delivery and great price!

This brand is typically a good brand. But the cartridges are very expensive.

[This review was collected as part of a promotion.] Great price very cheap

They are a true Brother product and works very well for a Brother printer!!

Exactly what I ordered.

One and a half years with printer that uses these, have gone through 3 of these toners. PRINTING 1500-2000 PAGES PER YEAR. Do the math, that's only 1000 pages per toner. Not 3000 like they claim. They'll respond with ISO testing standards, affected by several factors, etc. Well, most of those pages are blank spreadsheets. Just printing the borders of 31 cells. So don't try pulling that with me. Just acknowledge you're lying about how much this toner yields. Brother seems to be following HP's route. Start off with good stuff to build a good reputation, then use that reputation to get away with selling stuff that's nowhere near worth it.

I was taken aback by the life of the original cartridges, and am hoping the new extended capacity cartridges will be better. I reduced the image density (from the control panel) in the hopes of extending the life of all the cartridges. What I was surprised to find was that once the black cartridge signaled to be replaced, the other colors soon followed suit. I have never had a color printer do this. We specifically went mostly B&W, reserving color only when needed. Now, I am 300 pages in to the cartridge, and the black is showing 90%. Even with density turn back down? Is it real? Time will tell.
