The Kyocera Mita TK-552 New Compatible Black Toner Cartridge is a product that really improved on my printing as it produces clean and consistent printouts besides having a high print capacity of 7,000 pages. I did not have a hard time when it came to fitting and taking out this toner cartridge from my printer. In addition, it was shipped within 3 days of order and has a one year warranty which actually did guarantee that it was a manufactured with precision and that I am covered in case it refuses to work. I am so happy with this toner cartridge since it turned out to be a good investment.
