VISA-FREE TRAVEL TO IRELAND USING FAMILY REUNIFICATION VISA

Hi, i just want to ask if someone here experienced travelling to Ireland or other EU countries without having to show a visitor visa? I have read on some sites that  Family Members of an EEA/EU residents are entitled to a visa-free travel to Ireland as long as you have the FAMILY MEMBER OF AN EU NATIONAL resident card or i think it's the one we call FAMILY REUNIFICATION visa in Norway. Has anyone experienced this? Thank you.

Norway is not EU.....
