Don't know anything about them -BUT- if you are looking for 3rd party ink options may I suggest that you find someone with your exact machine that is running that ink and talk to them. Ask them if there were/are any problems, color shifts, printing on certain medias, of if they've had any supplier problems getting those inks. That is what I did and ultimately I made my decision based on their input - not the promises of the ink manufacturer/salesman.
In fact, you should be able to call that company and ask them to speak to 2-3 customers who are running your type of machine with that ink and get their feedback. *Also be sure to try to stress that you want to talk to someone near your neck of the woods, not necessarily same state, but maybe a 5-6 state radius.
If they can't do that - I'd walk away.
