Have you heard about?

Have you ever heard about Leptovox? Well I have never before I checked it out. I was reading about it and they guarantee that you can loose up to 14 pounds in only seven days. They say if you don't then you can have the product for free. What kind of miracle is this anyways. I was also reading the reviews and I seen that it says that it gave many people energy and made their skin look really nice. So what do you think? Is it worth a try?
