Good and very cost-effective solution

Have the cartridges now depleted almost half and really can not find a visible difference to the original cartridges.
Expression of standard paper OK.
Expression on Photo Paper (satin finish) without complaint.
Nothing rubs off and the paint dries as fast as the original.
The level is well recognized.
Of course, the Canon software recognizes the imitations and are some features not free, as with original cartridges.
For me, it plays a subordinate role, because I do not use these tools!
Would soon order a second set!

Conclusion: strong buy recommendation
