I was rather septic on the purchase of these cartridges. 10 cartridges for the price of one, I was not expecting much. So I wanted to test them, I did not have much to lose. I use it now for several months and I am very satisfied! They are fully recognized by the printer. The print quality is very good, I have not found ink that spreads on paper. Color side is also great. I change them can be a little more often than the Canon cartridges, but it is not obvious. And they could be filled twice unless they remain five times cheaper. I have not yet used all the cartridges, but for now I have not been defective.
For the next refueling cartridges I thus apportion those on it.
