"so happy this last for 10 years! 25 years old(i had it inserted a year ago)now i gave it 9/10 due to the heavy bleeding for the first 3-4 months, once you get over that hill its amazing. no hormones which was very important for me personally. so if your looking for a very effective birth control, look no further! just expect heavy bleeding for at least a few months, it gets better you just have to let your body adjust to the new device."
