EZ Ink123 gives no customer service. I emailed three times without a response and live chatted once. The live chat was worthless, since they will not warrant anything beyond 60 days and are not flexible with this policy. I dont even try to use the cartridge within 60 days. If I could give a zero rating I would, but the worst I can do is a one. Do NOT order anything from them. If you have a problem they will not respond.
