If printing is a necessity, this cartridge works like most others, meaning that high yield no longer is what it used to be.

The cartridge works fine.

Good cartridge, however not as black as some of my past cartridges.

Is this cartridge defective

Genuine ink cartridge at a better price than local office supply store!

These 'High yield' cartridges are touted to last through 600 pages of printing

Also, b/c the cartridge is somewhat transparent, you can actually see the amount of ink left in the cartridge

The cartridge I received did not work in my brother printer MFC J870

Cartridge didn’t work

After trying a couple of new, cheap cartridges, I decided to break down and pony up for the real Brother ink here.

Cartridge was faulty

The cartridge is leaking

I can get cheaper cartridges elsewhere.

Excellent Cartridge for and excellent printer.

Tried using cheaper cartridge and they are no good

Great cartridge.

My previous all in one used the cheaper cartridges and that was the downfall of the machine.

The cartridges are very easy to install, and the ink is crisp and black with no smudging

I don't print much, but this cartridge was obviously defective

My son specifically stated a Brother unit as they have one of the most cost effective replacement ink cartridges.

Every day I need to "clean" the cartridge or else it prints with lines

Bought two black cartridges, but only one worked

I received one defective cartridge (the printer would not recognize that it had been inserted), and even though it was past the allowed return date, Amazon Customer Service gave me a full refund.

Bought another cartridge and that one did work.

Excellent high yield ink cartridge.

I can only conclude that the cartridge is bunk.

I am pleased with the quality and highly recommend these ink cartridges.

If you only use your printer occasionally, I recommend the LC101 because idle cartridges tend to clog which requires cleaning and alignment.

I like that I can replace only the cartridges that are low in ink (black, and each color are separate cartridges)

Since a firmware update for my Brother MFC-J450DW inket printer, these cartridges fail to be recognized by the printer.

This was a quick delivery and the cartridge was very easy to install.

Brother makes the worst ink cartridges.

My printer is in use every single day, mostly for black and white printing and these cartridges are very easy to install and produce good results.

Tried several compatible cartridges, none work.

It is so nice not to have to frequently purchase expensive ink cartridges for a printer from that company Carly Fiorina used to manage.

I printed more pages trying to clean the cartridge to get it to print clearly than actual papers that needed printing

This is just a great oem replacement cartridge

I received a defective cartridge.

Love the high-yield cartridges

Good source of genuine, new Brother cartridges

Contrary to what the description says, this cartridge DOES work in the Brother MFC-J6520DW.

The cartridges fit and work but colors not as good as the real thing.

Good ink cartridge at a fair price.

Great ink cartridge!

The cartridge performs as well as the original when printer was purchased

These cartridges did not work- "ink cartridge not detected' message.

I definitely prefer the High Yield cartridge over the regular one, as I do feel I get more from it.

Great high yield cartridge

Genuine Brother ink cartridge

Great cartridges

Amazon offered a good price for an excellent, brand name cartridge.

Ok....the first cartridge I received, had issues.

These cartridges work great and they are easy to install.

The second cartridge is perfect.

It was exactly the right ink cartridge for my printer.

High Yield cartridge does not run out of ink as fast as the regular cartridges which makes me happy:) Will be purchasing all of my replacement ink cartridges for my printer from AMAZON, as long as they keep the prices competitive with other online stores and local "box" stores.

I never have a problem with genuine Brother ink cartridges.

Also, b/c the cartridge is somewhat transparent, you can actually see the amount of ink left in the cartridge

Works as it should.

Works as it should.

High quality product and works as it should.

Very pricey, and doesn't last long, but it works as it is intended.

It worked as what I would call gray scale for a week

Used it for a few photos and pleased with the results.(Putting this here as well as with the printer I purchased at the same time).
