As described in previous reviews I can only recommend this original product here. By using the original cartridges of Canon, I hope a long life of the Canon MX860 (mittlerweilse the 5th year). In addition, so far I have not had problems with the correct identification of the chip. The ink is always completely consumed by my printer type without rest. Long periods of storage in this package represent no problem. In some cases the cartridges are more than a year with me in the drawer.
