Cartridge World / Poor Service Poor Products
I use 6 to 7 toner cartridges in my business. In 2011 I had some problems with the cartridges from Cartridge World. Each time they told me they would check into it and let me know. They would then call me back and tell me the cartridge was just empty. Therefore I started tracking the cartridges purchased from Cartridge World. I found that I was having a 33.3% failure rate. One of the cartridges that I returned wasn't used for more than 40 pages and upon return they said it weighed full. Then later they called me back and said they made a mistake and it was empty.
This Cartridge World has some technical problems with their cartridges or they are lying to their customers and being dishonest. In any event their Cartridges are poor quality and have a high failure rate. They will not service or warranty their work. I recommend not buying toner cartridges from this business.
