First of all, it's still in trials. Second of all, what should set off an immediate alarm is the claim of "100% effectiveness" (and safety for that matter, what if the doctor screws up and cuts your tubes?).
In fact, if you check the Wikipedia article for this thing you will see a large amount of controversy and problems that the article just ignores. That alone is enough for me to not consider this seriously. It would indeed be nice if this form of birth control were real, but as things stand it's just vaporware for medicine.
It's really amazing to me how many people believe anything they want to hear...
No, thanks.
