They well packaged and well recognized by my Canon 5250 printer.
I put a reserve still on their autonomy: I still feel (pun!) They run out quickly, I change quite often, even if it may come my limited use. Indeed the ink dries if we do not use it and the printer performs cleaning when the lights and spends unnecessary printer.
Coté quality, no complaints, photos and documents are rendered correct.
The price that is less than a Canon cartridge pack, here there are 4 packs.
