Opinions on NuvaRing?

My gynecologist recommended it to me, but I'm not really sure how I feel about it.
I'm worried it will cause cramps (sometimes tampons make me have horrendous vaginal cramps), and that my partner will be able to feel it. In addition, I was severely depressed when I was on the pill for 6 months...
Do you guys have any thoughts/experiences with it?
