J uses these cartridges for printer Canon MG 8250 I have bought 4 packs of 10 cartridges for printing course for 1 year and a half. These cartridges work very well. It is possible that in case of use of the printer over a long period, a nozzle cleaning is required with START cartridges. j also uses canon of original cartridges in quantities much lower. I do not print note al difference.
