I believe it is genuine Brother product

I will only use genuine Brother toner after a negative experience with generic toner

Well this is a brother

This is why I always buy GENUINE BROTHER TN580 cartridges

Plus the Brother HL-5240 is much faster than anything I have used in the past.

Works on brother printers, cheaper than local.

Packaging did not look like genuine Brother product.

This is not some lower quality toner that they will tell you is just as good as the Brother product.

I'm not sure that this is a genuine Brother product.

Glad to replace it with a genuine Brother cartridge.

Would recommend authentic brother products.

I ended up returning it to them and buying this Brother toner cartridge that works perfectly.

Second, there seems to be an attempt to fool consumers into thinking this is genuine Brother product.

Brother TN580 lasts a long time and never leaks, never streaks, and always makes a crisp clear copy

In the lab where I work printers are under heavy load from multiple users, and Brother HL-5250DN is the best of all printers we had so far

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