I'm a bit late to the party but... I have one & it's greeeat
Mines more for medical reasons as I had a very very extreme period which was causing me to have to go home from work etc etc (never had pain like it in my life, the only thing that's made me go white as a sheet from the sheer pain)
I go from that to NO period at all, so i'm a very happy lady ^_^;
Although sometimes if I'm lying down on my side with my head on my arm it gets a bit sore. The procedure itself was fine (just an injection and a small hole site left which healed fine)
