Yes, tried a "free trial period" with them to prove how good they were and lost my shirt. They told me those were just "free plays" anyhow and that I'd make real money if I jumped on board for their "real" package. Uh huh!!! No thanks.
Ive tried them before, as well as their other sister site, National sports service, discount sports picks, etc. and ive never made any money of their services. Seems that they either cool off when i get on board or they just make up numbers to get new clients and dont care if people are satisfied or not, because there is no guarantee once they have your money.
