Compatible Canon CLI-551MXL Magenta High Capacity Ink Cartridge

What more can I say about The Cartridge Shop products than to say that I am always pleased with my purchase, pleased with the cost, particularly because my dear wife uses my printer a lot to print copy's of her own painted Water Colour paintings. I have found that if you use the correct printing paper you will always get good prints. One probably unknown aspect of buying from The Cartridge shop is that if you have a problem printing with their cartridges or even your printer they are prepared to help and give you advice on what to do to resolve your problems. In all the years that I have been purchasing ink jet cartridges from "The Shop" I have only had one problem with one cartridge which was resolved very quickly.I always advise my friends to buy their cartridges from this company with one provision and that is this. After using compatible cartridges, use one of the Printers own recommended cartridges after using five of the compatible cartridges. I was told this by an acquaintance who used to work in a shop selling all sorts of cartridges, as the original cartridges have something in them that cleans all the necessary parts of the printers head.
