The first two cartridges were fine and each worked well, the third looked fine but shortly after placing the 3rd toner the machine began to creak and groan and sounded as if all the wheels were breaking apart.

Its been a month since I bought this cartridge and its been working well

The cartridge worked great for a while.

This works great with some modifications

Keep up the good work!!

This one works great.

Item was received quickly with no hassles; seems to be working well; we'll need to see how long it lasts.

The first one works great.

It's an authentic Brother product that is working as designed
