"i&#039;m 19, average weight and i&#039;ve been on the patch for 10 months. i love it because you only have to remember it once a week. i hand had zero side effects and it works great. the reason i gave an eight rather then a ten is because its not a 100% effective. i use it with condoms. they say its 99% but i don&#039;t believe it. if you don&#039;t want to get pregnant always double up contaceprives or at least use withdrawal. i don&#039;t think anything should be used alone unless its an iud, tieing the tubes, or a vesectamy. so double up! but overall the patch makes it easy and not tedious to use a second method."
