This cartridge works well in my Brother HL-5140 B&W laser printer, and has a higher capacity (prints more pages before running out of toner) than the one that came with the printer; it costs a bit more but prints many more, so a lower cost per page.

No loud pops when I print (like it did with a "Brother compatible" cartridge)

Very good service and cartridge is worked fine

I recommend this replacement toner cartridge for a Brother Printer

Wish they made printers and cartridges like this now-a-days

Cartridge worked as expected.

It makes clear, clean prints, and the cartridge is easy to change.

Printer is cheap but cartridge is expensive!

This cartridge works terribly

I have tried commercially refilled cartridges and off-brand compatibles.

This cartridge is quite easy to install

I purchased this genuine cartridge to replace a discount toner cartridge.

Don't waste your money and purchase "compatible" toner cartridges

n't duplex).The TN570 is an expensive cartridge, but worth it (I paid 75.00, delivered).The printer functions as new again

This is the worst toner cartridge I ever purchase

Worked exactly as it should.
