I confirm the previous comments. It is exceptional enough to say these generic cartridges work as well as the original for a really affordable price! I'm glad I kept my bill so you can find the references and recommend a new pack that day (or two, so I'm quiet for six months, one year). Installation: no recognition of my Pixma MP610 issue Color: I see no difference with the original. packaging: a small sealed bag, which ensures good conservation cartridges in time, easy to cut. Less waste than large blisters original. Delivery: well-protected products in a compact box. Fast delivery. Only downside: I need to order on Amazon that optimizes its tax and pays very little tax in France, I do not valid as a citizen. Given the Amazon turnover realized with our purchases, the least you would accept to pay taxes accordingly.
