I've been using the patch since just after it hit the market. I haven't experienced any negative side effects from it, and it has also done its job (although I also use condoms too). I am a very light skin tone, but the patch is still an off color for me. However, I wear it in a place that no one other than my man gets to see, and believe me by the time he gets there, he doesn't care about the color. My only mini complaint is that it can get stuck to your clothes, so it won't lay/lie
flush to my skin. It has never come all the way off, but it can get annoying. Hope this helps.
