I don't really like them. Mainly because every time somebody gets one, they are always running the little metal barb thing across the outside of their lips and it's so annoying! Plus, they seem kinda tacky and trashy. Don't get one, unless you just have to have one.
i had one twice I'm getting it again after braces. but most people don't care much for them.
I don't mind them. When I was younger I wanted one. But then I just couldn't do it because of the profession I want to be in, plus my life long dream of being a "role model" for my indigenous people. So they're OK (:
