Because it's made for Brother, BY Brother, it works perfectly. It may be more expensive than generic knockoffs, but the quality of the knockoffs always leaves at least a little to be desired. Besides, using non-OEM (original equipment manufacturer)will void the warranty, so you'd have to save a LOT of money to even break even!

[This review was collected as part of a promotion.] Walmart had the best price and I only use genuine Brother in my printer.

Fast delivery and good price

Good price for item.

This is very high quality ink which makes printing look better and less smugging and smearing.

Great for the price

Arrived promptly. I like the size and usually like Brother brand inks. However, this cartridge has an issue. I must clean the ink heads before every printing or large lines of missing text appear across the page.

was not included in big shipping box, came in separate small envelope even though it was supposed to be part of the box shipment. ink box was smashed and torn but still obviously resealed. no stale dating on either ink box or ink cartridge which means I risk trashing my printer if I try to use it. will return
