Does anyone have any information about the products offered by Primerica? Do they work?

I'm looking for some back ground on the products offered by Primerica and whether or not they have actually worked for people. What I'm not looking for is a Primerica rep to come on here an tell me how good it is to work for the company. I want to know about the products not a job. How do the products compare to what else is out there?
