Never heard of it. What does it do?

it is suppost to lighten or stop your periods by using a radio frequency energy that destroys the lining of your uterus. in the brochure it says that it can also cure or curve pms. my doctor did say that in about 5 to 10 percent of his patients it doesnt work at all due to the safety mechanism. if your uterus is too thin or soft then the machine wont turn on. i was just curious if anyone has had it done and has any side affects good or bad.
