I do not understand: - These cartridges are perfectly compatible with my Canon MG5350 which in addition detects and manages to give me the filling level, - They do not run and do good impressions (text and photos) - Autonomy is very correct, - But they are very cheap. What's the catch then? Ben looks like there is none. But why original cartridges or other generic brands are (good) and more expensive (much) less reliable? A real mystery to me ... In short I love it!
