Advantage No. 1 compatible cartridges, is to be more affordable ... The problem No. 1 compatible cartridges (especially for the HP models), it is not always reliable ... C is what happened in my case: the color cartridge ran without problem but for black and white, nothing to do (a "missing or damaged cartridge" message appeared immediately after installation). And this is where the supplier's quality has its importance! Ink Club has really been up: informed by email of the problem, immediate response and sending a replacement cartridge (which works very well that one) and a prepaid envelope to return the defective cartridge. Then I say "bravo"! Ensuring the buyer receives good (whatever happens) a product that will give him ultimately satisfaction is all we ask! It's done, and it's perfect!
