Authentic Brother product
Genuine Brother cartridge made to Brother’s very standards.I’ve tried cheaper generic cartridges but too often they leak powder. No such issues with Brother’s own cartridges.For those of us concerned about disposal and recycling they also come with a postage page return envelope for the used cartridge.

Did not work, had to return.
Having had this on the shelf for a month before use, very frustrating to find it wouldn't print. It just left blue stripes across the page. Had to go through the pain of Brother Service, but eventually was sent a replacement that worked. During the fault finding I bought a new drum for £107 which obviously didn't solve the problem, and I now can't return which is very frustrating.Surely there's no excuse for a printer cartridge not to work!No reply as to why it wouldn't.

Genuine Toner
This is genuine Brother toner.All genuine toners are expensive but it gives good colour when printing. Having purchased a new printer I didn't want to mess it up with copy toners.

Very easy to fit. Takes about 15 seconds.
These cartridges are very easy to replace. I get a message on my phone saying replace soon. When they run out, you just press the button on top of the printer and pull the tray out. They pop in and out very easily.

Low levels of ink
The levels of ink that were sent with the printer, was significantly lower than these inks purchase

Brother Printer Toner Cartridges
Genuine Brother cartridges at a better price than direct from Brother. In past have been tempted by other makes but Brother set up their machines to not accept them. A very costly error!
