Someone tell me about Nuva Ring !

So I'm on birth control, for about 3 years now, & I have been realizing the past couple of months that the non generic brand I've been getting (while at school I get a different brand then at home) & it's made my skin bad , not terrible but bad, & the pudginess.

Tell me how you like Nuva Ring. Did it affect your skin, weight, emotions ? Do you like it better than any other method ? Any other points I should know ?

Thanks !
