cartridge very good price and cheap

I bought there a + 1 year. The cartridge starts to show signs of clogging after 1000 leaves black marks on white, printed text with white stripes, very bad contrast in gray (tracks, scratches, dark spots). In short, great for 800-900 sheets after it should be changed, it remains a shame when 17% toner and a capacity of 1,500 sheets to estimate.
Do not print black and white photos, the rendering is ugly.
