I print VERY casually (1-2 x/week) but these cartridges lasted only about 10 months instead of the 2.5-3 years with other cartridges. In the meantime, my papers have been coming out with multi-colored dots. It looks like I'm printing on confetti paper. Since I've never had this issue before I can only attribute the problem to the inferior products sold by InkJetSuperstore. I'm now an EX-customer!
