Review on LxTek Compatible Canon 137 Toner Cartridge Replacement - 4-Pack for ImageClass Printers (Black) - Ideal for MF236n, MF247dw, D570, MF227DW, MF229DW, LBP151dw, MF217W, MF216N, MF249dw, MF232w by John Brazington

I bought a Conon MF236n printer. This is a great printer that runs in the $100-$150 range. However, branded replacement cartridges cost over $50 each. They are refurbished and I have been using them at work and at home for several years. I believe they are the best of several restored options. Of the dozen or so purchased, there might have been one that didn't work very well. But usually they are just plug and play. For the price, the random problem is understandable and not even worth contacting the seller.
