Has anyone gone to a school like UEI, Kaplan, or a similar school and had success?

I am trying to find the best school to go to but am finding pretty bad reviews online for a lot of them. I know someone who had a bad experience is more likely to leave a review than someone who had a good experience is so I wanted to ask if anyone has gone to one of these school and had success during their time there and also finding a job after??? Also what was the cost? They are very secretive about costs they always want me to come to the campus and talk with someone who I know is more of a salesperson than a counselor. Please help! I will choose best answer!
