Follow this link and read it.... Its probably biased but worth the look.
Quoted from http://quixtarcriminals.blogspot.com/:
This Blog is in honor of my son Jonas. You can find all the information you need, to know Quixtar spells doom for you and your family, in the end. There are so many things wrong with this organization, why risk it? Though you can find in depth information on all of Quixtar's shady practices and possible illegalities, my focus is the personal stories of how really bad it can get, how you can lose everything of value to you and your family. It's a crime!
