Toner Tech- High Yield Remanufactured OEM Toner Cartridge Set Replacement for Brother TN-115 Set (Complete Set)

One out of the four cartridges were unrecognizable when replacing the toner in my Brother printer. I contacted Toner Tech, they replied in a timely manner and said they'd replace the cartridge with a call tag for a replacement. Sounded great but they haven't sent the replacement and haven't responded to my emails. I ended up ordering a single replacement cartridge on Amazon for 50% less than what I originally paid that is doing fine. BTW, I informed TT that I would leave this feedback if they didn't contact me.

If I could give negative stars I would. Not only do these not work but, they actually damage your printer. You can print with them but, the cartridges continually leak - giving you terrible splotchy output. And instead of getting better, they leak worse and worse over time. So, initially you keep going because you hope that things will get better but, they never do. Things get bad quickly! Eventually, you can barely read text because of how bad the output quality is. Then you finally throw them out because you have given up. Then, you put regular brother toner cartridges back in but, it's too late. The bad toner ink has damaged your fuser roller. Even though you cleaned the mess up, you will never get a decent page out of your printer ever again. And, a new fuser assembly will cost more than the printers worth. So congratulations, you killed your printer...

I’ve installed two out of the four and they seem to be working well. No streaks, good prints, etc.I’ve not installed the other two cartridges as the ones they replace are not yet out. I’d really like to be able to install them and test them right away. However, these units don’t come with any of the covers for the ends of the cartridges, so I’m afraid that once I test them, they may make a mess, if I try to take them out again.Again, the cartridges that I’ve tested so far seem great. But here is some minor advice--*When you get the new toner, mark on it (or on a label or tape stuck to it) where and when you got it. That way you know not to order the same bad toner again.*Don’t order too much ahead, as it harder to return it, if you discover it bad and many months have passed.*Make or find a test sheet with all the toner colors on it and test the toner when you put it in. That way, you can quickly identify a bad one.It would be really, really nice to have a way to test the new units immediately, so you can return the bad units.

Avoid - my brother printer has never had the color cartridges replaced as I am not a high volume printer. However I knew the time was coming so I purchased these to be ready. Today I opened the packages and immediately noticed I should have never purchased. All the units had leaked toner, so I had to invest in a can of compressed air. The color ones work (for now) the black unit makes an interesting piece of art by implanting speckles all over the page. Thank goodness my old black one was still serviceable. I will end up throwing away this printer as I can see the color ones are still leaking - only a matter of time.I cannot get a refund because I waited too long.Don't purchase - don't repeat my mistake.

This was a recycled set and it wasn't clearly stated when I purchased the product. The bargain I thought I was getting was realy no bargain at all. The black leaked all over and made a huge mess of my printer. I had to throw the blackAway and re purchase a new not used recycled black toner. With all the aggravation including mopping my floor I still saved money but if your printer is near a carpet, stay away from this product

You know, This is truly amazing. A few years ago I had bought a set of cartridges for my printer from someone else. They were the same price as these but they were "Brother Compatible" after about a month of using I started having streaks and smudges on all of my printouts. I saw these and saw that they were Brother Brand and only $99. So I bought them, cleaned up my printer(took it outside and air hosed off all the parts) and installed these cartridges. After 3 months of using I am still getting clean crisp printouts. I have started printing out pictures like I used to when I first got the printer. I AM SO HAPPY, I wish I had gotten rid of the "Bargain" cartridges a long time ago. I almost threw out my printer because I was so disgusted with it.If you have a Brother Laser Printer and need replacement cartridges, GET THESE, They are just like the original, and don't cost an arm and a leg.

The yellow toner cartridge is leaking and leaving the pages with yellow on them.. basically ruining everything I print.. I've hardly printed on this at all maybe 300-400 pages. I'm trying to figure out who to contact since Amazon does me no good on this.****** Follow up ****** They never did replace the yellow cartridge after several e-mails to them.. have no idea what the warranty is must be 30 days or less.

Yellow Toner cartridge never worked. It leaves yellow splotches and yellow toner trails along both edges of a page every time I print. Moreover, when I opened the toner tray in the printer it looked as if the yellow cartridge had exploded in there, so I cleaned it and tried again to no avail. Moral of the story is even if the other 3 cartridges end up working just fine, one bad one can render the whole thing useless, making this a bad deal
