What's the Deal With Quest?

Ok so it seems a lot of people are entering this supposedly lucrative business of network or multilevel marketing, namely this company called Quest. If you've been approached, probably one of your friends or acquaintances has tried to wow you with this fascinating presentation about the business. You can become a millionaire with the least effort possible, all you have to do is buy JD500 worth of their so-called unique online products and you're in. Now what you have to do is keep making these presentations for people in order to recruit them so they'd buy the products in turn. And the more people you recruit, the more money you make.

Frankly I've done some research about it, and the whole thing is just too fishy, I'm not buying it. Their products are incredibly overpriced and you can only get them if you want to get in the business. Old members have to recruit new members in order to make money, but won't this have to stop at some point? Eventually the new members will be unable to recruit any more members, the very basis of what is called a pyramid scheme. Moreover, they fascinate you with their endorsements from FIFA and United Nations (even the Vatican!) but when I actually looked it up, I couldn't find a source other than the Quest websites themselves to verify this information.

Now some people I know have actually made some money already, but I fear they're making it from their friends and family who may very well lose. So my question is, does anyone know anything about this?
