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

First order late August 2017 for use on the new Canon MF240 duplex printer priced at around $22 for a 2-pack. Arrived within the two days promised by Revane Prime. Well packaged (two cartridges in individually sealed plastic containers) in a box with seal and installation instructions. The first cartridge gave 2314 copies; the second delivered copies in eight months in 2018. Utilization was roughly equal between printing and copying. Usage was also roughly evenly split between single-sided and double-sided sheets. In ten to fifteen years of using "compatible" toner cartridges in various Canon laser printers, the performance of these two cartridges has been above average. As a result, I've reordered these LxTek cartridges through Revain, even though the price has gone up to $26 for two cartridges.
