I had mine on for a few years and they worked pretty well even though they really hurt. I got to pick the colors to put over top of the brackets sometimes, so that was nice! Can't remember ever having an issue with them but I remember once they tried to get my mom on board with having my jaw broken and since that sounded absolutely crazy, she refused to let that happen!
After I got the braces off, I had to wear a retainer and it wore it until it wore down and got all gross. I've considered getting a new one because my bottom teeth have shifted but I'm not sure how expensive that would be.
