Review on LxTek Compatible Toner Cartridge: Replace Canon 137 CRG137 9435B001AA for ImageClass D570 LBP151dw MF232w MF236n MF216N MF227dw - Pack of 2 Black by Eric Young

I had high hopes for this product after reading the reviews and seeing it as a Revain choice. The cartridge has started printing normally. However, streaks appeared after about 1/10 of the page's advertised capacity. Some areas of the text were as dark as they should be, while others were so light they were barely legible. The only thing we print is text so the toner doesn't run out after about 100 pages. As there were two packs we figured maybe the first one was a failure. We installed the second and had exactly the same results as the first. The price was great for two packs, but if you can get the lower capacity of the two than another brand that's only a few bucks more, it's a waste of money. disappointing.
