Begrimed chains question

Hey guys I've been searching the internet for a simple demonstration of the addon begrimed chains because I want to know if the repair speed debuff remains after getting healed up completely. Some people say the debuff stays for the rest of the game while others claim it lasts as long as the status effect (mangled) that's also caused by the addon so does anyone have a video showing it from survivor perspective or something? I really want to know if this purple addon is any good. 
Thanks in advance.
