I use the cartridges (multiple deliveries) for 2 years now for my Canon MG 5350th The cartridges can be used without problems as the originals and are accepted by the printer without prob. There is also no problem (for example, clogging of the nozzle) to the pressure head. When printing on paper, I could not tell the difference from the original printing ink. The look on photo paper is in my opinion a little worse than the original, because the ink does not run optimally. For occasional photo prints, the quality is sufficient. The paint dries quickly. The cartridges are transparent so you can see the level of delivery and you do not have the feeling to be drawn at this unbeatable price on the table. Conclusion: The value for money is great !!
