Lol this is an interesting topic. I actually checked the link and did more research before coming to post here. I searched youtube videos and it seems like a good enough, legitimate business. Search for yourself.
As for me, I have a good job working in an embassy for the last three years. My salary is not typical for the average Nigerian at all and I am grateful to God for that but I have come to the conclusion that every company is a pyramid business. Think about it. No matter where you work, unless it is your personal business, you will never be the CEO, Ambassador, President, or whatever title the top level person- the oga at the top decides to give himself sad, but true that is why I encourage anybody who is willing to work hard for somebody else to think outside the box and join any of the good self/ home businesses out there that appeal to their interest and put that work in. People are making mad money from FLP, Herbalife, WV, and so on. I joined FLP in February and I can't say how it has impacted my life. Upon all the money the Embassy is paying me toh but the job may not be there forever. Invest in yourself o!

If you are willing to work hard for somebody else for peanuts, good luck to you!
