I had them. Got them off a little over a year ago. Even though I hated them when I had them on I am still happy I had them because now I will have straight teeth when I am older =)
Yep. i have this kind that are like this weird kind of wire that doesn't need tightening, because it bend to the shape it originally was (which is the place they want my teeth to be), so they don't need tightening.
