I havent had it, but I can tell you I am choosing not to get it because I've read too much research on uterine scarring etc as a result of IUDs and since I plan to have kids in the future I don't want to have another thing to worry about. My BFF also got it and while she's OK with it now she said the pain of getting it was shocking (and she is tri-athlete, toughest girl I know) and radiated down to her knees for a few days after insertion. She also had the same problem as others with the sting being too long etc.
