The cartridge leaks yellow toner and creates a mess in the printer.

Great toner!

Expensive, but after trying two "compatible" toner cartridges from other manufactures that were poor quality, I went back to Brother toner for my Brother laser printer.

Reliable toner cartridge

No issues, the toner works fine

Great Toner!!

The TN221BK toner arrived when promised and like all my Brother OEM products, worked perfectly.

As always toner is far to expensive.

This black toner DOES NOT print as dark as it should.

Great toner at a fair price for OEM.

The other replacements I tried had faded and striped printing and dumped toner inside my printer - so no deal

This part is a genuine standard yield black toner cartridge and works as it is supposed to.

Based on a great deal of history and experience with 'compatible' toners I always go with the manufacture's toner.

Just as good as the toner that came out of the box

This toner is wonderful

Genuine Brother toner is the way to go

it's toner, it works, print print print

The font is still dark so it doesn't seem like the toner is about to run out.

Toner works, it's genuine, it is the same price as a new color laser printer.

Good toner.

Great toner

No issues, the toner works fine

my printer keep telling me change toner, finally, replace toner.. not working...

I always think toner is very expensive.

Brother Genuine TN221BK Color Laser Black Toner Cartridge

It's a really efficient toner.

The toner has been working great.

I need to print top quality labels with this and these do not print as dark as other toners

This is a compatible generic toner cartridge for the Brother printers, but is not a Brother brand cartridge

Overall, nothing really surprising here (good or bad); just a standard toner cartridge for a typical price.

Toner is expensive, it's just how life goes, but this cartridge for our home printer was easy to replace and should be good to go for...who knows, 1500-2000 pages

Genuine Brother toner works as expected.
