I replaced my old cartridge which was attracting toner ink and turning it completely black. This new cart. works and the cost was affordable.

Update: my most recent delivery of this remanufacturer's toner cartridge gave me one or two black stripes across nearly every page I printed. Fortunately (or unfortunately, depending on your viewpoint) I had had a string of bad luck with these replacement cartridges, so I've developed the habit of keeping an old cartridge around that still has some pages left in it. That's now loaded into my printer while I return this one. When the new one arrives, I will pop it straight into the printer to see if it works, and if it does, I'll seal up the old backup cartridge for its next use. Don't even THINK of buying one of these remanufactured jobs and putting it away in a supply closet. Test it the day it arrives!

What follows is my original, four-star review.

I just now ordered a spare cartridge from this vendor in hopes it will prove as good as the one I got last month. I have been doing a run of 150-page documents lately, and of course I am uncertain how long a given cartridge will last. As you probably know, the OE toner cartridges are priced at north of $45. For years I bought from an online vendor for about $20 and thought that was a great deal. More recently, the same vendor was pushing $45 cartridges, so I searched for a better deal on Amazon. (My printer is five years old, so I have no hesitation about using off-brand cartridges in it.) This is what I found. The print quality is excellent--even, acceptably dark, and no smearing. I am being conservative and giving it a four-star rating because of course I have no idea how long it will last. Usually I expect to get a year out of a cartridge, but lately my print jobs have been more demanding, so I figure six months on a ten-dollar cartridge would be a very good deal. I will try to report back when it begins to run out.

My printer gave me a notification that it's non-HP cartridges, but somehow I was still able to get it to work.

Instead of just replacing the cartridges every time, I wanted to try to cleaning them and reusing them. This worked like a charm! You have to make sure you rinse the cleaned cartridges really well, but otherwise it works great.

I am really enjoying the fact that I paid way less for this replacement toner cartridge than OEM. I especially like the fact that there were instructions on maximizing the number of copies not only for this cartridge but for the one that was in the machine. I will definitely buy this item from this seller again.

It made a loud grinding sound when printing and chewed up the last page consistently.  I installed the old cartridge and there was no noise, so its not the printer's fault.

Not sure - having problems with my printer since I installed this - but it may not be the cartridge.

The printer states that I am running out of ink and should change the cartridges and I just put in these new ones from Office World.
The ink is fine. No problem.

I did initially have a problem with the toner.  The first one I opened was very noisy when printing, almost like it was having problems turning.  It definitely was making a squealing sound.  I emailed the seller, but while waiting for a response decided to try some WD-40 on the end where it seemed to not want to turn smoothly.  That quieted the cartridge right down.  I am happy with the print quality, and hope I will be able to get the estimated amount of pages printed before it needs replaced.  If it lasts, I will be happy to reorder.

I've been using printer cartriges from different sellers/manufactures/remanufacturers for years without incident until I  used this cartridge.  I inspected the cartridge before putting it into my printer and it appeared solid and without any defects.  From the beginning it began spewing excessive toner into my printer, ruining the drum and other printer parts, which a tech says now need to be replaced.  However, labor plus new parts will total more than I paid for the printer when I purcahsed it.

Lesson learned: only use cartriges from reliable manufactures/remanufactures that have extensive positive reviews.

I have a Brother MFC -7360N printer. After the original toner ran out I purchased more toner from one of those cartridge refill stores. The owner promised me that it was good for 2000 copies. After about 200 copies it started printing very light. I took it back to the store and was told "We haven sold that type of cartridge in years, are you sure you bought it here?" Because it was about six months later, I couldn't find my receipt to prove I bought it there so I just lost $50.00. OfficeMax sold it for $80.00 so I decided to give this refill a try. It was so easy to refill, and so far works great, you can't beat the price. Just make sure you follow the instruction, and dump all of the old toner out before you use the refill.

Update 1/22/17: I love this ink so much that I had to give a update on how well It is performing. I make on average about 100 to 150 copies a month and so far I have not had to use another refill yet, and the ink is still a solid black. I can only speak for my self but I can't really tell a difference from this ink and the original ink. For those who the ink didn't preform well maybe they bought the wrong ink, or didn't follow the instruction correctly. It's nice to be able to just print what without worrying about using too much ink.

After a time, the toner cartridge began leaking toner onto my letters and pictures.

When I changed the toner cartridge, the printing was not as vibrant as with the Brother brand cartridges.  I changed all cartridges so I think it might be the toner itself.  Might have to go back to using Brother brand.

After a few uses, the ink cartridge  is being detected as "out of ink".

Reinstalling the cartridge does nothing. Shaking the cartridge, I can hear plenty of ink inside.

Not sure what is causing this, this is the first replacement ink I ever had problems with.

I have used 2 of these cartridges and never experienced any problems. The print across each page was even and there was never any streaking of ink.  As with all cartridges that I have used, when it is nearly out of toner, there will be a vertical portion along the length of the page where the print is fading. This is an indication to me that it is nearly time to replace the cartridge. I can get a several more sheets by shaking it 2 or 3 more times before I must insert a new one in it's place.

I have no idea how many sheets I have printed from the 2 cartridges.  I average 1 cartridge per six months. Most of my printing is master copies of classroom tests and quizzes as well as multiple articles from the web.

I am ordering the same cartridge again.

This cartridge replacement is better than the previous one I purchased from another company at a slightly lower price. It prints as well as the Samsung toner cartridges.

I've printed about 50 pages with the new toner cartridge thus far, and I can't tell the difference between the old (original OEM) and new (LINKYO compatible) cartridge.

I will note two items that might help others:
1.  I had to print about 10 pages before the lightness of the text that led me to replace the toner in the first place completely disappeared
2.  I had to do a "toner cartridge reset" to get the "low toner" indicator to disappear.  These are the steps for my MFC-L2470dw:
- Turn on printer
- Open front cover
- Push and hold the # button (not lit) until screen shows Reset Menu"
- Select TNR-STR-A"
- Select yes after Reset prompt

Hope this helps!
