ToBeter Replacement for Xerox Phaser 6510 WorkCentre 6515 Toner Cartridge (1 Black, 1 Cyan, 1 Magenta, 1 Yellow)

Facts: Ordered to have one hand when needed. Yesterday, they were needed. Inserted Yellow and printer continued to show "Install Yellow Cartridge". Inserted the Black and printer continued to show "Install Black Cartridge". The printer would not work. In summary, the cartridges didn't work. They are useless. Do not buy these if you want to be able to continue working when you replace the toner. Seller has offered to send a replacement box of toner from a new shipment they say have been "checked and tested". I have to give them a higher star rating for making the effort to reach out to me.

doesn't print as much as other sellers ink, even though it's "supposedly" the same thing.I keep track of when I change my toners and from whom I'm buying it from and so far, the magenta from ToBeter only lasted me 2 weeks exactly. On average, each toner I use last at least 1 month if not more. I haven't used the rest of the pack from this seller, but when I do, I wouldn't be surprised if it lasted me around the same amount of time. Tentatively, won't be purchasing it from them until I try out the rest of the colors.

Arrived quickly and packaged ridiculously well. Easy to install and work very well. I don't see them running out soon.

I have a brand new machine...replaced with the black toner of this set and have been having troubles with quality of the prints. Toner does not seem to work with this printer very well.

After installing this, i have had nothing but trouble.Printer has multiple error messages that xerox cannot seem to resolve. Luckily it isunder warrenty and they seem to be committed to seeing us through the problem, but we have been dead in the water for 3 weeks now. not worth it!

Outstanding product delivered ahead of time.

Three of the four cartridges worked fine.

Great buy for the price! Thank you!
