Used for 2,5 years, really lowed my libido after some month of use, get me a complete loss after some years. Later suspended for this same reason and because I had a vaginal yeast infection (not used precautions, such as vaginal ovuli with lactobacilli, useful in every hormonal contraception use). Tried years later, but had big problems with increased vaginal discharge (got a vaginal irritation caused by the costant humidity in my lady parts). Very practical (you can forget about it for 3 weeks), but lots of collateral effects (at least for me). You have to try ii to discover if it's good for you or if gives you difficult side effects (it's very personal). If none, can be a very good choise.
